At 3am the maths starts. If I fall asleep now, I still get three and a half hours. Then four o'clock comes, the number shrinks, and you lie very still, as if stillness were the same thing as sleep.
By the third month you've tried the tea, the magnesium, the melatonin and the blackout curtains. Some of it helped for a week, then the nights went back to how they were. All of it missed the thing that keeps insomnia going, and it's something you've been doing every night to help yourself sleep.
The harder you try, the more awake you get
Insomnia usually starts with a real cause, like a stressful month, a new baby or a bout of pain. The cause passes. What stays are the habits you built to cope with it: going to bed earlier to "bank" rest, lying in on Sunday, staying in bed at 3am because getting up feels like admitting defeat.
Every one of those habits makes the next night worse, and the reason is sleep pressure. From the moment you wake, a chemical called adenosine builds up in your brain, and the longer you're up, the heavier it gets, until your body clock opens the window that lets it pull you under. An early night or a lie-in spends that pressure before you need it.
Nine hours in bed for six hours of sleep means the sleep gets spread thin across the night, with long wakeful gaps in between. And those gaps happen in one specific place, which your brain files away. A few hundred nights of that, and the bedroom sets off alertness all by itself. Pavlov's dogs learned to drool at the sound of a bell; your brain now switches on at the sight of your pillow.
This is why effort backfires. Sleep arrives when you stop steering, and lying there willing it to come is steering.
If this has only been going on for a few weeks, you're at the easiest point to stop it. Keep getting up at your usual time, however the night went, and skip the lie-in, the afternoon nap and the early night. They feel like recovery, and they're the habits that turn a bad month into chronic insomnia.
The part most advice leaves out
There's a short course that retrains the way you sleep, known as CBT-I, and it has one big advantage over sleeping pills: the pills help while you take them, and the retraining keeps working after you stop. Few people have heard of it. Most end up with pills or a sheet of sleep tips. If you're on sleeping pills now, the retraining works alongside them. Get proper guidance before coming off them, because stopping suddenly can bring a few rough nights back.
Where it does get described, it's usually as relaxation and breathing exercises. Those are a small part of it. The parts doing the heavy lifting are two techniques that sound backwards the first time you hear them: spending less time in bed, and giving the bed one job. On its own, cutting your time in bed does about as much as the whole course, at least in the first months.
Dark room, no screens, no late coffee: the sleep tips are all good habits. On their own, once insomnia has settled in, they rarely fix it.
Spend less time in bed to sleep more
People resist this one, so the logic comes first. You compress your time in bed down to roughly the amount you're actually sleeping. Sleep pressure builds higher, the broken sleep pulls together into one solid block, and your brain relearns that bed means sleep. Once the block is solid, you widen the window.
Start with a sleep diary. For two weeks, note each morning when you went to bed, roughly how long you slept, and when you got up. Estimates are fine.
Find your number. It's your average sleep. If you're in bed eight and a half hours and sleeping about six, your number is six.
Set your window to that number, with a floor of five and a half hours. Pick your wake time first, because it's the anchor, then count backwards: six hours with a 6:30 alarm means bed at 12:30.
Hold the wake time seven days a week, weekends included. It's the rule that retrains the clock. Until the window opens, stay up even if you're sleepy at 10pm, in low light with something dull to do.
Widen it slowly. Once you're asleep for most of the time you're in bed, about 85 to 90 percent of it, add 15 minutes. Keep widening until the extra time stops turning into sleep.
Here's how the first few weeks tend to go. Say your diary shows eight and a half hours in bed and about six asleep, so your window becomes six hours, ending at your usual alarm. The first few nights you're yawning long before it opens and fighting to stay up, and the next day drags. Within a few days you're tempted to give up and go to bed early.
That's the moment to hold on: the tiredness is sleep pressure building, which is the whole point, and it's where most people quit, right before it starts working. Somewhere in the second week you start falling asleep faster and waking less. By the third, you're asleep for most of the window, and bedtime moves fifteen minutes earlier.
Judge it by how solid the night is, and give the hours time. The first things to change are how fast you fall asleep and how long you lie awake in the night. Total sleep barely moves at first, and the hours come back as you widen the window. Before they do, the night stops being a fight.
If you'd rather follow the programme on paper, the workbook by sleep psychologists Jack Edinger and Colleen Carney walks through the same diary, window and weekly adjustments one session at a time.
Get proper guidance before you start if you have bipolar disorder, epilepsy, suspected sleep apnoea, or if you drive for a living or operate machinery. The short-term sleepiness matters more in those cases, and a gentler, guided version is the safer way in.
Give the bed one job
The shorter window builds the pressure, and this part breaks the link between your bed and lying awake. Go to bed only when you're sleepy, which feels different from tired: sleepy means your eyes are closing. Keep the bed for sleep and sex, and move the scrolling, the work, the series and the arguments somewhere else.
If you're lying awake and getting frustrated, get up. Go to another room with dim light, read something undemanding, and come back when you're sleepy again, as many times as the night needs. Keep the fixed wake-up time from above whatever the night was like, and skip daytime naps while you're retraining, because they spend the pressure you need at night.
Set the room up once and stop tinkering. Dark, cool and quiet: use or an eye mask for the light, and earplugs or steady background noise if your street is loud. Past that point, a better bedroom adds very little.
Answer the 3am maths
The countdown in your head runs on one belief: a short night means a wrecked day. Test it against your own record. Find the days in your diary that followed your worst nights. You were slower, shorter-tempered, and the afternoon dragged. Still, you got through every one of them, and some went fine.
People with insomnia do tend to score a little lower than good sleepers on memory and problem-solving. Their attention, reaction speed and many other skills hold up just as well. The day after a bad night is harder. It's rarely the disaster the 3am maths predicts.
So when the maths starts, answer it: I've had nights like this before, and I managed the day after. Then turn the clock to the wall, so the countdown has nothing left to feed on.
The worries about tomorrow are easier to deal with before bed. Spend five minutes writing tomorrow's to-do list, and make it specific: the email you owe, the call about the car, the form due this week. It helps people fall asleep faster than writing about what they've already done, and the more specific the list, the faster they drop off. If the racing mind is the main thing keeping you up, by sleep psychologists Colleen Carney and Rachel Manber is built around it.
What the day does to the night
On their own, the usual daytime habits rarely fix chronic insomnia, which is the sleep tips point from earlier. Alongside the window, a few of them make it work faster.
Morning light is the strongest. Get outside in the first hour after your fixed wake-up time, for a walk or just your coffee on the step. Light is the main signal your body clock uses to set itself, and a regular dose of morning light eases insomnia a little.
Movement helps as well, and regular exercise tends to improve sleep. Evening exercise is fine, and even helps slightly, with one exception: hard training that finishes within an hour of bed.
Caffeine lasts longer than it feels. Coffee six hours before bed still cuts sleep noticeably, and for a regular cup the safe gap is closer to nine hours. For a 10:30pm bedtime, that means your last coffee by about half past one.
And if hot flushes and night sweats are breaking your nights, the method still works through them. Most women with hot flushes who work through this retraining have put their insomnia behind them within about two months. The flushes themselves are worth getting looked at too.
Where the remedies fit
Supplements are extras on top of the method, and most of them do a little rather than a lot. What each one is thought to do tells you who it suits.
Magnesium is a mineral your nerves and muscles need in order to work and then relax. When you're low in it, cramps and twitching can show up at night, so it makes most sense if your diet is short on it. In older adults it seems to help people fall asleep a little faster.
Saffron extract seems to work through the body's night signal. People taking it end up with more melatonin in the evening, the hormone that tells your body night has started, and rate their sleep better. Tart cherries work along the same lines, since they contain melatonin themselves, and drinking the juice raises it in the body. Kiwi is the gentlest of the lot: it's rich in serotonin, the brain chemical your body turns into melatonin.
Ashwagandha works on the other end, the stress response. It's a herb from Ayurvedic medicine that lowers cortisol, the main stress hormone, and people taking it sleep a little better, especially those with diagnosed insomnia. Rare cases of liver injury have been linked to it, and it's a poor fit with thyroid conditions.
Melatonin itself is the body's darkness signal, telling your clock that night has begun. That's why it helps after jet lag or a shift change, when the clock is set to the wrong time. In ordinary chronic insomnia the clock is usually fine and the bed is the problem, so melatonin has little to correct, and valerian's effect is hit and miss. If you take any regular medication, check any herb against it first, since ashwagandha, St John's wort and several others interact with common drugs.
When it's something else
Some insomnia belongs to another condition, and no routine fixes that. Get it checked if you snore loudly, gasp, or someone has seen you stop breathing, which can mean sleep apnoea, or if your legs crawl or jerk when you lie down, the sign of restless legs. The same goes if low mood or constant worry came before the sleepless nights, or if the problem started with a new medication.
If you've slept badly at least three nights a week for three months, your insomnia counts as chronic, and it's worth looking for this retraining by name. Structured online programmes and the workbook above make it easy to start.
The bed has to be retrained
Everything you tried was an attempt to add something at night: a pill, a tea, a smell, a gadget. What works takes things away instead: the extra hours in bed and the nightly fight to fall asleep. And it holds one thing still: the time you get up.
It will feel wrong for a week, maybe two. Keep going, and a night comes when the 3am maths never starts.
Start the diary tomorrow morning. In two weeks you'll know your number, and you'll have a window to protect.
