It is 2am. You have tried the lavender spray, the podcast about Roman aqueducts, and counting sheep until the sheep unionized. Now you are lying in the dark, typing "free CBT-I" into your phone, wondering whether the fix for your sleep is going to cost you a fortune.
Good news first: most of CBT-I costs nothing but attention. The method is a set of behaviors, not a product, and nobody owns the idea of getting up at the same time every day. The less exciting news is that the free version asks a lot of you, and there are a few situations where doing it alone is the wrong call.
Here is the honest map: what you can do tonight for free, the free resources worth knowing, how to check whether someone else will pay, and where going fully DIY tends to run out.
What you can do for free, starting today
CBT-I - cognitive behavioral therapy for insomnia - is built from a handful of techniques. Every one of them can be started with a pen, a notebook and the alarm clock you already own. The full at-home sequence walks through them in order; here is the budget version.
1. Keep a sleep diary
For one to two weeks, change nothing and just write it down each morning: when you went to bed, roughly how long it took to fall asleep, how long you were awake in the night, when you woke, and when you got up. Not the fitness tracker's opinion. Yours.
This feels like homework, and it is. It is also the foundation every later decision is built on, because the memory of a bad night is a dramatic storyteller. "I didn't sleep at all" often turns out, on paper, to be a few broken hours. How to keep a sleep diary properly.
2. Fix your wake time
Pick a rising time you can keep every day, weekends included, and keep it no matter how the night went. Yes, Saturday too. Your body clock does not know it is the weekend, and a lie-in to "catch up" quietly pushes the next night later.
3. Get out of bed when you are awake
If you are lying there awake and getting frustrated, get up, go somewhere dim and dull, and come back when you feel sleepy. The goal is to stop your bed from becoming the place where you rehearse worrying. Fold laundry. Read something mildly boring. Do not reorganize the garage. What to do at 2am, specifically.
4. Build a wind-down
Give yourself a buffer before bed: lower lights, put work away, something calm and repetitive. This is not the treatment on its own, but it makes the other steps easier to keep.
5. Set a sleep window from your diary
Once you have your baseline, work out your average total sleep time and use it to set your time in bed, counting back from your fixed wake time, with a floor you do not go below. This is sleep restriction, and it will feel too short. That is the point: it builds sleep pressure into a smaller window. The arithmetic, written out.

What the free version actually feels like
It is worth being clear-eyed about this before you start, because the free version of CBT-I is not a gentle spa weekend. It is closer to training for something.
The diary weeks are the easy part. You fill in a few lines over coffee, you notice patterns you had not spotted - the late-night email that keeps you up, the Sunday lie-in that wrecks Sunday night - and you feel quietly productive. Nothing is asked of you yet except honesty.
Then the sleep window starts, and the alarm goes off at the same time on a Saturday morning after a rough night. Every part of you wants to stay put. This is the moment the method is built around: getting up anyway is what rebuilds the sleep pressure for the next night. It is also the moment most people quietly negotiate with themselves and lose.
Expect to feel more tired before you feel better. Expect a night or two where you get out of bed, sit on the couch with a dull book, and think, with some feeling, that this is ridiculous. That is normal. The trick is to treat the diary as the judge rather than any single night. One bad night is weather. A trend across weeks is climate, and the climate is what you are trying to change.
A few small things make the free route easier to stick with:
- Keep the diary by the kettle, not the bed. Filling it in the morning, away from the scene of the crime, keeps it accurate and stops you clock-watching at night.
- Tell one person what you are doing. Someone who knows why you are up at the same time on a Sunday is less likely to tempt you back to bed.
- Plan the out-of-bed spot in advance. A chair, a blanket, a low lamp and something boring to read. Deciding at 3am is harder than deciding at 3pm.
- Review once a week, not every morning. Daily scoring turns the diary into a report card. Weekly review turns it into data.
Free public resources worth knowing
Outside your own notebook, there is a decent amount of trustworthy, free material - you just have to look in less glamorous places than an app store chart.
Government and health-system websites. Public health bodies publish plain-language explanations of insomnia and of CBT-I, often with diary templates. The National Heart, Lung, and Blood Institute's insomnia page and the NHS insomnia page are good, sober starting points.
A CBT-I app from the US Department of Veterans Affairs. The VA publishes a CBT-I app designed to support treatment with a provider. Its page on the VA mobile apps site describes what it does and who it is for.
Professional society patient pages. The American Academy of Sleep Medicine runs a patient education site that explains insomnia and its treatment in plain English, without trying to sell you anything.
One warning: "free sleep app" and "free CBT-I" are not the same thing. Rain sounds and bedtime stories can be pleasant, but if an app never asks for a sleep diary and never sets a sleep window, it is not doing CBT-I. The difference, explained.
