A Treatment Most Patients Have Never Heard Of
Chronic insomnia affects roughly 10–15 percent of adults. Patients suffer through years of poor sleep, often cycling through prescription sleeping pills and over-the-counter aids that work modestly at best and carry meaningful risks.
Cognitive behavioral therapy for insomnia (CBT-I) is more effective than any sleeping pill for chronic insomnia. The American College of Physicians, the American Academy of Sleep Medicine, and other major societies recommend it as first-line treatment for chronic insomnia. Yet most patients with chronic insomnia have never been offered it — they get prescriptions instead.
At Zimmer Medical Group, we discuss CBT-I as the foundation of insomnia treatment and refer to providers and resources that deliver it.
What Chronic Insomnia Is
Chronic insomnia involves:
- Difficulty falling asleep, staying asleep, or waking too early
- Symptoms occurring at least 3 nights per week
- Symptoms persisting at least 3 months
- Daytime consequences — fatigue, mood disturbance, concentration problems, reduced performance
Acute insomnia (lasting less than 3 months) often resolves with addressing the precipitating cause. Chronic insomnia tends to perpetuate itself through behavioral and cognitive patterns that benefit from specific intervention.
Why Pills Are Not First-Line
Common sleep medications include:
Benzodiazepines (Temazepam, Lorazepam, Others)
- Habit-forming with regular use
- Tolerance develops, requiring higher doses
- Dependence and difficult discontinuation
- Increased fall risk in older adults — see our benzodiazepines and older adults article
- Cognitive impairment, particularly memory
- Increased dementia risk with long-term use
- Daytime sedation
Z-Drugs (Zolpidem, Eszopiclone, Zaleplon)
- Similar concerns to benzodiazepines
- Sleep-related complex behaviors (driving, eating, walking while asleep — well-documented with zolpidem)
- Tolerance and dependence
- Memory effects
- Increased fall risk
- Initially marketed as safer than benzodiazepines but evidence has accumulated of similar concerns
Antihistamines (Benadryl, Tylenol PM, Many "Sleep Aids")
- Diphenhydramine and similar compounds
- Significant anticholinergic effects
- Cognitive impairment, particularly in older adults
- Long-term use associated with increased dementia risk
- Tolerance to sedative effect develops quickly
- Can worsen restless legs and other sleep disorders
Melatonin
- Useful for circadian rhythm disorders and jet lag
- Modest effect for primary insomnia
- Generally safe for short-term use
- Long-term safety data limited
- Quality of products varies (it's a supplement, not a regulated medication)
Newer Medications
- Suvorexant, lemborexant, daridorexant — orexin receptor antagonists; less concerning side effect profiles but still recommended as adjunctive rather than first-line
- Trazodone — used widely off-label; modest evidence; daytime sedation common
The fundamental issue: sleeping pills can help short-term sleep but don't change the underlying patterns driving chronic insomnia. When pills are stopped, symptoms typically return.
What CBT-I Actually Is
CBT-I combines several evidence-based components:
Stimulus Control
- Use the bed only for sleep and intimacy (not reading, TV, scrolling)
- Go to bed only when sleepy
- If unable to sleep within about 20 minutes, get out of bed and do something quiet until sleepy
- Get up at the same time every morning regardless of sleep quality
- No daytime napping (or very brief, very early naps)
Sleep Restriction (Sleep Compression)
This is often the most powerful component:
- Calculate average actual sleep time over 1–2 weeks
- Restrict time in bed to that amount (with a minimum of 5 hours)
- This temporarily creates sleep debt, building sleep pressure
- As sleep efficiency improves, time in bed is gradually extended
- Often produces dramatic improvement within 2–4 weeks
Cognitive Restructuring
- Address unhelpful beliefs about sleep
- "I must get 8 hours or I'll be miserable tomorrow"
- "If I don't sleep tonight, I'll fall apart"
- "I have to make up for last night's poor sleep"
- These thoughts increase arousal and worsen insomnia
Sleep Hygiene Education
- Comfortable sleep environment
- Avoid caffeine in the afternoon
- Limit alcohol (disrupts sleep architecture)
- Exercise regularly (but not late evening)
- Wind-down period before bed
- Address light exposure (bright light morning, dim evening)
See our sleep hygiene article for more detail.
Relaxation Training
- Progressive muscle relaxation
- Diaphragmatic breathing
- Mindfulness-based techniques
- Address racing mind at bedtime
How CBT-I Works in Practice
A typical CBT-I program:
- 4–8 sessions over 6–12 weeks
- Initial assessment
- Sleep diary tracking throughout
- Weekly adjustments based on diary data
- Behavioral changes implemented progressively
- Cognitive work integrated throughout
- Tapering of any sleep medications often part of the process
Where to Access CBT-I
In-Person Therapy
- Behavioral sleep medicine specialists
- Some psychologists trained in CBT-I
- Some sleep centers
- May be limited in availability in some areas
Telehealth CBT-I
- Increasingly available
- Same evidence base as in-person
- More accessible
Digital CBT-I
- App-based and online programs with strong evidence
- Sleepio — extensively studied; available in some healthcare systems
- Somryst — FDA-cleared prescription digital therapeutic
- CBT-I Coach app — developed by VA; free; effective for many patients
- Sleep Reset, Restore, others — various commercial options
Digital CBT-I is increasingly viewed as an excellent first-line option, particularly when in-person therapy isn't accessible.
Self-Guided Programs
- Books like "Quiet Your Mind and Get to Sleep" by Carney and Manber
- "Say Good Night to Insomnia" by Jacobs
- Workbooks and structured programs
Self-guided CBT-I works for motivated patients but often less effective than therapist-guided.
What to Expect
The honest realities of CBT-I:
- Sleep restriction often makes things worse before they get better — patients may feel more tired in the first 1–2 weeks; this is part of the mechanism
- Improvement typically begins within 2–4 weeks
- Significant improvement by 6–8 weeks is typical
- Effects persist long-term — unlike medications, gains tend to be sustained
- Requires commitment — daily implementation of recommendations
- Effective for the majority of patients — including those who have failed multiple medications
When Medications Are Reasonable
Despite CBT-I being first-line, medications have a role:
- Short-term use during acute stress
- Bridge therapy while accessing CBT-I
- Patients who can't access CBT-I
- Selected long-term use in patients who have failed other approaches
- When combined with CBT-I
The goal should usually be the lowest effective dose for the shortest reasonable duration, with regular reassessment.
Special Considerations
Older Adults
- Particularly important to avoid Z-drugs and benzodiazepines (fall risk, cognitive effects)
- CBT-I works as well or better in older adults
- Address underlying causes (sleep apnea, restless legs, nighttime urination, pain)
- Address natural age-related changes in sleep architecture
Patients on Existing Sleep Medications
- CBT-I can include planned medication tapering
- Don't stop benzodiazepines abruptly
- Coordinate with prescribing physician
- See our benzodiazepine deprescribing article
Patients with Coexisting Conditions
CBT-I works for insomnia coexisting with:
- Depression and anxiety
- Chronic pain
- Substance use
- Other sleep disorders (after addressing primary disorder)
Treating insomnia often improves coexisting conditions too.
What Else to Address
- Sleep apnea — must be ruled out in patients with insomnia
- Restless legs syndrome — see our RLS article
- Mental health conditions — depression, anxiety
- Pain conditions
- Medication-related sleep disturbance
- Substance use — alcohol, caffeine, others
- Circadian rhythm disorders
When to See Your Doctor
- Insomnia persisting more than 3 months
- Daytime impact from poor sleep
- Insomnia with snoring, gasping, or other features suggesting sleep apnea
- Insomnia with leg discomfort suggesting restless legs
- Currently using sleep medications and wanting to consider alternatives
- Looking for CBT-I resources and referrals
The American Academy of Sleep Medicine and the Society of Behavioral Sleep Medicine provide additional resources for accessing evidence-based insomnia care.
