Sleep Diary Template: What to Track Before Your Insomnia Evaluation
A sleep diary is one of the most useful tools in an insomnia evaluation. Two weeks of consistent notes gives a sleep specialist a clearer picture than a single visit interview can. The Consensus Sleep Diary, published in the journal Sleep in 2012 (Carney CE et al.), is the widely used standard. This article gives you a printable two week sleep diary template, explains what each column captures, and answers common questions about how to fill it out.
This guide was reviewed by Dmitriy Kolesnik, MD, a sleep medicine specialist at Vector Sleep Diagnostic Center in Rego Park, Queens. Vector has served patients since 2005 and runs 900 to 1000 overnight sleep studies a year.
Why Keep a Sleep Diary for Two Weeks?
A single night is too noisy to interpret. Two weeks captures workday and weekend patterns, day to day variability, and the effect of caffeine, alcohol, naps, and medications. Clinicians who offer cognitive behavioral therapy for insomnia (CBT-I) commonly use the diary to set the starting sleep window for sleep restriction therapy, one of the most effective insomnia treatments.
What to Track Each Day
- Bedtime: the time you got into bed
- Wake time: the time you got out of bed for the day
- Sleep onset latency: your estimate of the minutes it took to fall asleep
- Number of awakenings: nighttime wake ups you remember
- Wake after sleep onset: total estimated time awake between falling asleep and the final wake up
- Total sleep time: your best estimate of the hours you actually slept
- Daytime naps: time and length
- Caffeine: cups, and the time of the last caffeinated drink
- Alcohol: drinks, and the time of the last drink
- Sleep medications or supplements: name, dose, and time
- Sleep quality: 1 (very poor) to 5 (very good)

Do Not Interpret the Diary Yourself
It is tempting to add up the totals and reach a conclusion. Resist that. The diary is for your sleep physician to read alongside your full history, your medications, and any objective sleep testing. Patterns you would not notice on your own, such as wake time variability driving daytime sleepiness, or weekend recovery sleep hiding workday sleep loss, are easier for a trained reader to see.
Common Mistakes When Filling Out a Sleep Diary
- Filling it out at bedtime. Fill it out in the morning, while the night is fresh.
- Watching the clock. Estimates are fine, and clock watching tends to make insomnia worse.
- Skipping bad nights. Bad nights are the most useful data.
- Changing habits just because you are recording. The diary is a baseline, so keep your usual routine during the two weeks.
What Happens at the Visit
The sleep physician reviews the diary line by line, calculates sleep efficiency (total sleep time divided by time in bed), looks at night to night variability, and identifies behavioral and medication factors. Then they decide whether further evaluation is needed, including an overnight sleep study. The diary also sets the starting window for sleep restriction if CBT-I is offered. If you are preparing for a study, see our guide to the night before a sleep study.
How the Diary Drives Treatment Decisions
Two weeks of consistent entries lets the clinician work out measures you cannot see day by day: average total sleep time, sleep efficiency, mean time in bed, and night to night variability. Low sleep efficiency is one common signal for considering sleep restriction therapy. Large swings in wake time, even with enough sleep, point toward a circadian rhythm problem and a focus on schedule regularity instead. The diary turns a vague complaint into a measurable problem with measurable fixes.
The diary also tracks change over time. After starting insomnia treatment or changing a sleep related medication, a fresh two week diary shows whether the change is moving things in the right direction. You can read more about options in our guide to insomnia treatment and our Queens insomnia treatment overview.
Bring the Diary, Not the Interpretation
The most useful posture at a first insomnia visit is “here is what I noticed, you tell me what it means.” Patients who arrive with a written conclusion sometimes anchor the conversation to the wrong cause. Bring the raw diary and your questions.
If you already tried sleep hygiene, melatonin, magnesium, or over the counter aids, write down what you tried, for how long, and what happened. That history belongs with the diary even when it does not fit in the table.
Frequently Asked Questions
How long should I keep a sleep diary?
Two weeks is the usual length for an insomnia evaluation. Shorter periods are too noisy to show a pattern, and two weeks covers both workdays and weekends.
Should I use an app or paper for my sleep diary?
Either works. Paper avoids screen light at bedtime. An app is convenient, as long as it does not pull you into checking your phone at night.
Do wearables replace a sleep diary?
No. A wearable can add data, but your own account of how long it took to fall asleep and how you felt in the morning is what the clinician reads first. Bring both if you have both.
What if I cannot fill out the diary perfectly?
Bring what you have. Estimates are fine, and even a partial diary shows the pattern of your insomnia. Do not watch the clock to be exact.
Will I get treatment at the first visit?
The first visit is for evaluation and planning. Treatment recommendations follow a review of the diary, your history, and any testing the physician orders, such as an overnight sleep study.
Do I need an overnight sleep study for insomnia?
Not always. Insomnia is often diagnosed from your history and the diary. A sleep study is added when the physician suspects another condition, such as sleep apnea or periodic limb movements, that could be driving the poor sleep.
