Cognitive Behavioral Therapy for Insomnia does not begin with advice. It begins with two weeks of a sleep diary, a few lines filled in each morning, and everything that follows is read out of those pages. This is what the diary records, what your clinician sees in it, and how the treatment grows from there.
Each morning you note the time you got into bed, roughly when you fell asleep, how many times you woke and for how long, when you woke for good, and when you got up. It takes under a minute and it is deliberately approximate; clock-watching is one of the habits the program removes, not one it wants to install.
| What you write down | What your clinician reads from it |
|---|---|
| Lights out and the time you think you fell asleep | How long it takes you to fall asleep, and whether that is where the trouble lives |
| Wakings in the night, and their length | Whether your sleep is fragmented, and at what hour the body is giving up |
| Final waking and the time you got up | The early-morning stretch spent awake in bed, a quiet driver of chronic insomnia |
| All of the above, over fourteen nights | Your sleep efficiency: the share of time in bed actually spent asleep |
That last figure is the one the treatment turns on. Someone who is in bed for nine hours and asleep for five and a half has an efficiency around sixty percent, and that number, more than the total hours, is what a clinician uses to set the plan. A wristband cannot give it to you, because a wristband cannot tell a still, awake body from a sleeping one. Your own account can.
CBT-I is several techniques, but two of them do most of the work, and both are set directly from the diary numbers.
If the diary shows five and a half hours of actual sleep spread across nine hours in bed, the first prescription is a window of about five and a half to six hours, with a fixed rise time. It sounds backwards, and for the first week or so it feels it. The point is to concentrate sleep: a shorter window fills up, wakings shrink, and once efficiency climbs above roughly eighty-five percent the window is widened, a quarter-hour at a time, until you are sleeping the hours you actually need.
Years of lying awake teach the body that the bed is a place to be alert. Stimulus control unlearns that with a small set of rules: bed is for sleep, not for waiting; if you are clearly awake, get up and do something dull in dim light until sleepiness returns; the same rise time every day, weekends included. Followed consistently, the bedroom stops being a cue for worry and becomes a cue for sleep again.
Anyone with long-standing insomnia knows the sums. It is 2:10, the alarm is at 6:00, if I fall asleep now that is under four hours, tomorrow is ruined. The calculation is inaccurate, since a night of four hours is survivable and a night of dreading four hours is what actually wrecks the next day, but it is also self-fulfilling, because the alarm it sets off is precisely what keeps you awake. The cognitive half of CBT-I works on those thoughts one at a time: the belief that eight hours is non-negotiable, the fear of the bed itself, the sense that sleep is something you have to make happen. Your clinician does not ask you to think positively. They ask you to test the predictions against the diary, where they usually turn out to be wrong.
Most chronic insomnia has an ordinary beginning: a stressful winter, a new job, a bereavement, a run of night feeds. The stress passes and the sleeplessness stays. The clinical threshold is trouble falling or staying asleep, or waking too early, on three or more nights a week for three months or more, with a real cost during the day; but the more useful way to think about it is that insomnia becomes a habit the nervous system keeps running on its own. The things people reasonably do to cope, going to bed earlier, lying in, napping, watching the clock, are the things that maintain it. That is why a treatment aimed at the habit succeeds where waiting for the stress to lift did not.
The American Academy of Sleep Medicine's 2021 clinical practice guideline and the American College of Physicians' 2016 guideline both name CBT-I as the treatment adults with chronic insomnia should be offered first, ahead of sleep medication. The reasoning is straightforward: it works for most people who complete it, the benefit lasts after the sessions end, and it carries none of the tolerance or next-day effects of a nightly pill.
Whether that amounts to a cure depends on what you mean. A large proportion of people who finish CBT-I no longer meet the criteria for insomnia, and follow-up studies show the improvement holding a year or more later. What nobody honest will promise is that you will never have a bad night again. Everyone does. The difference after treatment is that a bad night stays a bad night instead of becoming the next three months, because you know exactly what to do with it.
You can start CBT-I while taking a sleep medication, and many people do. The diary simply records the nights as they are, medicated or not, and the program runs on top of that. If you would like to come off the medication eventually, say so at the evaluation: the usual sequence is to let CBT-I rebuild your sleep first, then reduce the dose gradually in coordination with whoever prescribes it. We do not prescribe, and we do not ask anyone to stop a medication on their own.
One more honest note. Sleep apnea and insomnia often occur together; we treat the insomnia, we have partners who treat the apnea, and our clinician coordinates any referral that is needed. If loud snoring or witnessed pauses in breathing are part of your picture, our sleep study guide explains how the two are told apart.
Massachusetts Sleep Center is a small practice, and that is on purpose: you are treated by a named clinician who reads every page of your diary, not by a rotating panel. Each of the clinicians below is licensed in the Commonwealth, trained in CBT-I, and experienced with the anxiety and low mood that so often travel with poor sleep. You choose who you book with, and you stay with them for the whole program.

Book with ChristineWe are in network with Aetna, Blue Cross Blue Shield, Cigna / Evernorth, Harvard Pilgrim, Medicare, Tufts Health Plan, UnitedHealthcare / Optum and Veterans Affairs Community Care Network. Sessions are covered as behavioral health visits, which on most Massachusetts plans means a therapy copay rather than a specialist referral. If you are unsure what your plan does, give us the details when you book and we will find out before your first appointment.
CBT-I sessions are billed as outpatient behavioral health, which is covered under the mental health benefit of every Massachusetts plan we accept: Aetna, Blue Cross Blue Shield, Cigna / Evernorth, Harvard Pilgrim, Medicare, Tufts Health Plan, UnitedHealthcare / Optum and Veterans Affairs Community Care Network. Your copay or deductible applies the way it would to any therapy visit. Tell us your plan when you book and we will check the benefit before the first session rather than after it.
Yes. Our clinicians are licensed by the Commonwealth, and that license reaches Provincetown, Pittsfield and Lowell exactly as it reaches Boston. We see most patients via telehealth with Massachusetts-licensed clinicians, and a limited number of clinicians also see patients in person; where you live changes nothing about the treatment, only about whether you ask for an in-person slot when you book.
Sleep hygiene is advice about the conditions around sleep: caffeine, screens, a cool room. It is sensible, and for chronic insomnia it is almost never enough, because the problem is no longer the conditions but the pattern your body has learned in bed. CBT-I changes that pattern directly, with a schedule and a set of rules built from your own diary, which is why it works for people who have already done everything the hygiene lists suggest.
Bring it if you like, but the diary matters more. Consumer wearables estimate sleep from movement and heart rate, and they are least accurate for exactly the people we treat: someone lying perfectly still and wide awake often scores as asleep. The diary records what you experienced, which is what the treatment is built on. Many patients find that putting the tracker in a drawer for the length of the program is itself a relief.
You leave with a written plan for the bad week that will eventually come: what to do when a stretch of poor nights arrives after an illness, a new baby or a stressful month, so that it stays a stretch and does not become a relapse. The gains from CBT-I are known to hold well after treatment stops, and that is largely because the skills go home with you rather than staying in the room.
Book an evaluation with a Massachusetts clinician and you will have your first diary pages before the appointment. If anxiety is a large part of what keeps you awake, ouranxiety therapy page describes how the two are treated together, and our treatment approach walks through the program session by session.
