What my sleep’s up to these days

February 26, 2010

The yellow bulbs in the hall are continuing to work well to light the bathroom, and the salt lamp is now confirmed for staying by the bed with a pink 15W pygmy bulb in it.  I should probably mention that there’s no reason why anyone should get a salt lamp, I just find them pretty myself, and they already filter out a certain amount of blue light (though not all) through being orangey.  It’s odd, the light looks deep pink if you put it on when the room is already lit, and more orange if you put it on when the room is dark.  It’s useful for when I want to sneak out of bed and get dressed when my partner’s still asleep, as it’s not bright or blue enough to wake him up, or as soft background lighting in the late evening.  Most useful of all, the cable has ended up positioned so that the switch is down the side of the bedside cabinet, about as easy to get to from the bed as is humanly possible, which saves fumbling around in the drawer to find the red bike light or similar. By the way, if you do decide that salt lamps are nice and go looking for one, ignore all the nonsensical health claims.  They’re just pretty lamps.

For some reason my sleep’s been a little odd over the last couple of weeks.  It may be because when my partner had a week off, our routines changed slightly.  I set the clock on the dawn simulator so that it would come on an hour later, as he said he wanted a bit of a lie-in but not to end up losing the whole morning.  I was often up and lightboxing before the dawn simulation as my wake-up time seems to be well-programmed, but it seemed to work well for him.  Then we went to bed an hour or so later than usual, which for me is strange as by now you generally can’t keep me up much past midnight however you try.  I’ve also been a lot more tired than usual during the afternoons and evenings, which I am now putting down to the ME/CFIDS having a minor flare.

Now that he’s back at work, I have been wrestling with the problem of my body’s sudden ardent desire to have siestas.  I’ve snapped back into my usual wake-up time with no trouble whatsoever, but I keep getting irresistibly sleepy later in the day.  I’ve tried fighting it for a few days, using the lightbox on a double stint in the morning and/or an extra session after lunch or early afternoon, and putting the little blue LED bulb into a clip-on light (which leaves it fully visible; at 1W it’s not so bright that you can’t look at it comfortably) and putting it by the bed or laptop from 9.30 am to 3 pm.  I’ve known that LED bulb to keep me quite wired at night if used up to 4.30 pm, but it didn’t do a thing for keeping me awake in the afternoons this time.  I wondered about adding a bit of 470nm blue light to my dawn simulation in the hope that it would get the message across to my circadian clock more effectively, and tried setting it for 15 min before and after the start of the dawn simulation.  When it actually came on, it turned out to be much brighter in a dark room than I’d expected, so I immediately turned it off.  I’d still be curious to try a blue or white LED dawn simulator one day.  The only blue one I know of was put together by this guy, and the only white one that’s meant to be any good (there are some cheap ‘n’ nasty things around) is the SRS320 by Morning Sunrise (Sunrise System), which not everyone likes as an overall unit.

I have now given in and realised that my body probably just wants more sleep by now, which can happen from time to time with ME.  I slept 16-20 hours a day the first year I was ill, not that I anticipate going back to that.  But someone on an ME forum did recently tell me that she feels best when she makes herself get about 11 hours’ sleep a day, which she guesses is due to her body’s increased need to do repair work during sleep, so I think trying some extra sleep is worthwhile.  I’m still aiming for my usual bedtime but am not too worried if we end up going to bed an hour later, though I’m occasionally lying awake for a little or waking up an hour before my alarm, something that’s less common for me these days.  The siestas are going OK, they range from 1-3 hours, though I suspect today may have been more like 4.  I originally tried sleeping with the curtains open and then went for closing them so that the room is pretty dark, in the spirit of having a proper sleep.  I think I’ll go back to leaving them open, I don’t want to end up messing up my sleeping pattern by getting my body to think that mid-afternoon is bedtime.  I’ve also gone back to herbal sleep aids at bedtime, since they never do me any harm, I just stopped them because at that point they were redundant.  I may as well get all the sleep I can if my body’s clamouring for it.

So far, my sleep at night is a little more broken as described above, but I no longer have the problem of having to torture myself to stay awake earlier in the day.  My overall energy levels are relatively low at the moment, so I think I made the right call on getting more sleep.  The only snag is that when I don’t remember to turn the phones off for my siesta I get woken several times (this is bringing back how awkward it is to sleep during the day), and when I do turn them off, I forget to turn them back on again!

Update

I’m definitely feeling better with more sleep, at least over the last few days.  I’m taking a fair bit of herbal stuff to knock myself out at night, last night it was one valerian formula, one 400mg valerian, and two 300mg passiflora/100mg chamomile capsules, but I’ve taken that sort of dose before and know that I’m absolutely fine with it, though I probably wouldn’t want to be relying on it long-term.  It’s far safer than temazepam in the short-term, though.  Last night it was mainly because I was concerned that my accidentally long siesta would mess up my treasured new sleep pattern and didn’t want to undo months of work. It took a little longer than my new norm to get to sleep (possibly – it’s really hard to tell), though far less than my old norm, and while I woke up at 7 am, I got back to sleep again.  Having a siesta has meant that I skip the stage of spending the afternoon trying to keep my eyes open, and while I’m still tired and ME-relapsy, I haven’t felt like a dead cat for a few days now.  It seems that I do indeed need this much sleep right now, even if my body has to be cajoled into getting it at the right times.

How to shift your bedtime/waking time to earlier

February 12, 2010

When I was using light therapy alone, I found that my 25 hour pattern shifted to 24 hours beautifully but that sooner or later, I would stay up too late and would end up stuck on falling asleep at 4 am or so again.  DSPS is a tough nut to crack.  This was in the days before I found darkness therapy, which has made my sleep/wake pattern rock solid, so here’s how I treated it at the time.

My preferred sleeping tablet when I need one is 20mg temazepam; many people find that 10mg is enough, but I need a higher dose.  While my GP advised me that I should be able to take it for up to a week, I found that taking it for a week straight caused rebound insomnia when I stopped, presumably because the ME/CFIDS makes me over-sensitive to medication.  I find that taking it for three consecutive nights is fine, so I work with that.  It’s entirely possible that I’d be fine with five nights, but I’ve never needed to try.

I would always recommend strongly that you discuss this with your GP.  They should be made aware of your sleeping problems anyway, even if you’re trying to solve them yourself, and sleeping tablets are fairly serious things, even the over-the-counter ones.  Discuss which sleeping tablets will best meet your needs, and if you’ve had a sleep problem for a while you’ve most likely tried several by now anyway.  Do tell them that you will only be using the tablets for a few nights in order to shift your sleep pattern, as otherwise they will be a lot more reluctant to let you have any meds.  I’ve managed to convinced a GP who’d never met me before to let me have four sleeping tablets for this purpose when it was an emergency (missed flight, unexpected night flight), and I doubt that he’d have let me have anything at all if I’d just wandered in to say that I was a bad sleeper and wanted some drugs please.

I’ve always been able to move my sleep back enough over three days using this method, but if I had needed to control a larger shift I would probably have done three days, waited a week, and then repeated the process.  My general lightbox treatment time is 45 minutes, but for this I would sometimes use a longer treatment time to help reinforce the circadian shift.  As far as I can recall, I used an ordinary alarm clock to make sure I got my light therapy at the right time the next morning, but dawn simulation would probably be even better.

Let’s assume that my bedtime is usually 1 am but has shifted to 4 am.

Day 0 – bed at 4 am, wake the next day at 12 pm.
Day 1 – sleeping tablet at 2.30 am for 3 am bedtime, bright lightbox at 11 am.
Day 2 – sleeping tablet at 1.30 am, lightbox at 10 am.
Day 3 – sleeping tablet at 12.30 am, lightbox at 9 am.
Day 4 – no sleeping tablet, lightbox at 9 am.

After that I would relax and use the lightbox whenever I woke up, instead of setting an alarm clock.  This method worked for me every time, including when I had to go on a night flight and deal with a 3 hour time difference to boot.

If you are using darkness therapy, you may not need the sleeping tablets at all.  Just put on the tinted glasses/switch over to orange lighting an hour earlier every evening.  The usual recommendation is to commence darkness therapy three hours before your desired bedtime, though some people find that they get sleepy too early if they do this.  Obviously getting sleepy too early is not a deterrent for DSPS sufferers!

For the above problem, I’d suggest starting the darkness therapy three or four hours before your current bedtime to begin with, and seeing what happened.  It may take a few nights to kick in fully.  Use the bright lightbox when you wake up.  You can wait until you wake up naturally, depending on how effective the darkness therapy is for you, or you can set an alarm so that you make yourself use the lightbox an hour earlier every day.  Since you’re not using sleeping tablets and therefore don’t need to worry about getting the process completed in a hurry, you can try shifting your sleep more slowly, even by 15 min a night.  Keep a diary of what you’re doing so that you don’t lose track.

If you have Non-24 Sleep-Wake Disorder, I’d suggest waiting until your circadian clock has shifted around to your ideal bedtime and waking time before trying anything, then hitting it with light therapy, darkness therapy and/or sleeping tablets to stabilise it there.  The sleeping tablets are a short-term measure, but the light and darkness therapies can be continued full-time and indeed should if you have a circadian rhythm disorder.

If your problem is jet lag or shift work, rather than a misbehaving body clock, you’ll have to experiment to find out what suits you best, and you may only need to use light/darkness therapies occasionally.  Sleeping tablets are best reserved for occasional use, so if you are going to be moving your sleep pattern every week or so, I wouldn’t advise them, and I would certainly suggest that you discuss this with your doctor.  Some companies give their night shift workers yellow safety goggles to wear when they go home in the daytime, so that the light on their journey won’t keep them awake.

If your problem is instead Advanced Sleep Phase Syndrome, then use bright light therapy in the evenings instead to keep you awake for longer.  I have absolutely no idea how darkness therapy would factor in here, but if you’re using it for other purposes (e.g. sounder sleep), I would imagine you would want to be careful not to start it too early in the evening, and remember that darkness therapy alone is unlikely to shift your body clock in the desired fashion.  Light therapy will be the key here.

For any of these problems, dawn simulation alone is unlikely to be enough to shift your body clock, at least in my experience, but may be very helpful in sticking to a good pattern once you have one in place.  I recently went back to dawn simulation, and while I had already stabilised my body clock using light therapy and darkness therapy by now, I think it may be adding a little extra help, and my partner is certainly finding that the dawn simulation makes it much easier to get up in the mornings.

Medication for sleep

January 26, 2010

Short-term medication

Doctors are reluctant to hand out sleeping tablets for good reason.  They’re most often highly addictive and can cause rebound insomnia, as well as the usual risk of side-effects.  They can be used sensibly, however.  If you’re going through a particularly stressful time such as a bereavement, sleeping tablets may be used for a few weeks.  If your bedtime has crept to far too late, sleeping tablets may be used for a short time (no more than a week; I can only do three days, then I get rebound insomnia), preferably in conjunction with bright light therapy, to move it back to where it should be.  Sleeping tablets can be scary things, so research side effects carefully and the first time you take a new med, make sure you can sleep in the next morning if need be.  I’ve tried Zolpidol and Zolpidem (Ambien), and while Ambien seemed to work OK at first, I tried it again and got hallucinations that night and was groggy for the next week.  I now use Temazepam 20mg for no more than three nights in a row, and probably do this a few times a year.  That said, now that I am nicely settled into darkness therapy, it doesn’t seem to be necessary.

Long-term medication

Most people shouldn’t be taking this, but instead improving their sleep hygiene and so forth.  If you have a sleep disorder that can only be helped by medication, it may be possible, though it should always be discussed with your doctor.  My sleep study showed that I don’t get enough deep sleep, as is common with ME.  I can improve my sleep hygiene until the cows come home, I’m never going to get enough deep sleep, so long-term meds make sense for people like me as long as I can tolerate them, and since I have only recently discovered darkness therapy, this is what my GP spent some time trying me on.  Rarely people will take the stronger hypnotics for long-term use, but it’s far from being a first port of call and I would not be able to do it myself.  Antihistamines and low-dose tricyclic antidepressants are common for long-term use.  I didn’t get on well with either: the antihistamines made me a zombie in the day but not particularly sleepy at night, while the amitriptylene (low-dose tricyclic) did great things for my sleep but caused too many side-effects.

I spent several months taking a herbal sleeping aid, Lifeplan Valerian Formula, before I discovered that I didn’t need it once I had the orange glasses for darkness therapy.  If you’ve tried herbal sleeping tablets before and found them useless, check the dosage you were taking, as most of the ones on the market are so low-dose that I doubt there’s more than a placebo effect going on.  The Lifeplan one has a nice reasonable dose, and some people take two capsules at a time.  Some studies suggest that valerian should be taken off and on to avoid building up a tolerance, so for half my cycle I took the valerian formula, and the other half (when I’m premenstrual and more likely to get anxiety) I took 600mg passiflora and 400mg skullcap at bedtime, both in capsule form by Biohealth herbs.  Now that the darkness therapy has kicked in, I’m just using the passiflora and skullcap, as they are useful to treat the PMS, won’t harm my sleep even when taken on top of darkness therapy, and would make me groggy if I took them during the daytime.  The main herbs for sleep are relatively well-researched by now and often come up as effective as benxodiazepines, so again do your research, make sure it’s a reputable manufacturer, and talk to your doctor about what you’re doing.  This should only be used long-term by people who have pretty much no other way of getting a good night’s sleep, however; if you’re reasonably healthy, just keep it for occasional use.

I’ve tried melatonin tablets but they didn’t do a thing for me.  They’re not used in the UK, which makes me fairly cautious of them to begin with, and it’s uncertain how well melatonin works when given in oral tablet form.  This site discusses the problems that can occur from taking melatonin tablets.  I prefer to use darkness therapy instead, where I’m stimulating my body to produce melatonin itself.  If it’s a long-term sleeping problem, I’d suggest trying darkness therapy before medication, unless you need the medication for other reasons anyway, such as low-dose tricyclic antidepressants for pain.
