Who should not do sleep restriction without a clinician
The VA/DoD patient guide lists seven situations where CBT-I needs to be tailored or delayed — this page helps you prepare for that conversation.
Safety screening checklistThe full tailor-or-delay list and what to discuss with your clinicianIn a small study, sleep restriction appeared safe for bipolar disorder when closely monitored, but regularizing bedtimes alone was often enough to improve sleep.
Excessive daytime sleepiness can signal sleep apnea or another condition that needs assessment before you restrict time in bed.
Sleep loss from restriction can lower seizure thresholds; your clinician may recommend a gentler approach like sleep compression.
If you’re in exposure-based PTSD therapy, the VA/DoD guide suggests delaying or adapting CBT-I so the two treatments don’t overwhelm your coping.
Active substance use can interfere with CBT-I progress; the guideline recommends addressing both concurrently.
An unstable medical condition may need to be stabilized before starting sleep restriction.
Acute mental health symptoms should be stabilized first; CBT-I can follow once you’re in a safer place.

What to expect over the next weeks
- First (weeks 1–2)Baseline diary and sleep window setup
You’ll track your sleep and set an initial time-in-bed window. Expect some extra daytime sleepiness — the AASM guideline notes this is common and usually temporary.
- Middle (weeks 3–6)Weekly adjustments based on sleep efficiency
Your sleep window expands or contracts based on how efficiently you’re sleeping. The typical rule: increase by 15 minutes if efficiency is above 85–90%, hold if 80–85%, decrease if below 80%.
- Later (weeks 7–8+)Relapse prevention and fine-tuning
The final sessions focus on maintaining your gains and building a plan for future flare-ups. Most people complete the core program in 4–8 sessions.
How the options compare
| Option | Evidence | Timeline | Best fit |
|---|---|---|---|
| CBT-I (therapist-led) | Strong | 6–8 weeks | Chronic insomnia; first-line per VA/DoD and ACP guidelines |
| Digital CBT-I | Good | 6–9 weeks | When no therapist is available; NICE recommends Sleepio in the UK |
| Sleeping pills | Mixed | Short-term | Acute crises; guidelines prefer CBT-I first due to tolerance risks |
| Sleep hygiene alone | Weak | Ongoing | Helpful as a CBT-I component, but not recommended standalone |
Discuss these options with your clinician using the CBT-I vs medicines comparison in the full guide.
When to get help
- Your insomnia is affecting your daily life so much that you can’t cope — see your GP for assessment (NHS guidance).
- You’ve tried changing your sleep habits for months without improvement — a clinician can rule out other causes and discuss CBT-I options.
- If you’re unsure who should not do sleep restriction on their own, the seven-item safety checklist in the guide covers every situation the VA/DoD guideline flags.
- You suspect sleep apnea (loud snoring, gasping) or restless legs — these need separate assessment before CBT-I starts.
Quick questions
Who should not do CBT-I sleep restriction on their own?
According to the VA/DoD patient guide, people with bipolar disorder, uncontrolled seizures, excessive daytime sleepiness, active substance use, unstable medical conditions, acute mental health symptoms, or concurrent exposure-based PTSD therapy should not attempt sleep restriction without clinician oversight.
If any of these apply, you can still do CBT-I — but a behavioral sleep medicine specialist should adapt the plan. Check the full safety checklist in the guide.
What if I have sleep apnea or restless legs — will CBT-I still help?
Suspected sleep apnea or restless legs syndrome should be assessed first, because these conditions can mimic or worsen insomnia. In one randomized trial, combining CBT-I with PAP therapy improved insomnia outcomes more than PAP alone in people with both conditions.
Ask your clinician about screening before starting CBT-I so you’re treating the right problem.
