Carla had been sleeping four to five hours a night for eleven months. Not because she didn’t want to sleep — she desperately did. Her body had simply forgotten how. By 2am she was wide awake, running through quarterly budget projections nobody had asked her to run at that hour.
Where she started
Day 1. Carla came with data: she’d kept a sleep diary for three weeks before starting. She knew her numbers. Average sleep onset: 78 minutes. Nighttime awakenings: two or three. Total time in bed: eight to nine hours. Estimated actual sleep: four and a half. The rest was anxious wakefulness.
The problem wasn’t just the fatigue. It was the cognitive spiral that had installed itself: every evening she anticipated the insomnia. And that anticipation guaranteed it. The bedroom had stopped being a place to rest — it was where she failed.
The first days
Sleep restriction was the first intervention and the most counterintuitive: reduce time in bed to six hours, regardless of how poorly she’d slept. The logic: build enough sleep pressure that the body relearns to associate bed with sleeping, not with watching the ceiling.
Carla hated sleep restriction. By day 3 she was the most exhausted she’d felt in years. Functional at work, but running on minimum. It felt cruel. She sent a message at 11pm: “This can’t be right.” She continued anyway.
Stimulus control was easier to understand: only get into bed with genuine sleepiness, not with the hope of it. If you’ve been awake for 20 minutes, get up, move to another room, quiet non-screen activity, return when real drowsiness arrives.
The turning point
Day 12. The first night Carla slept more than six consecutive hours in months. She hadn’t done anything different that night. The weeks of restriction and stimulus control had quietly rebuilt something in her circadian system. She woke without an alarm, with natural light. She spent a few minutes processing the fact that she didn’t remember being awake at 2am.
That day, she extended her sleep window by thirty minutes.
Where she is now
By day 21, Carla sleeps six to seven hours most nights. Bad nights still happen — roughly one every eight to ten days. But the anticipatory spiral has quieted. She goes to bed without calculating whether she’ll sleep. It doesn’t always work, but the difference between “I might not sleep well” and “I know I won’t sleep” is enormous.
Techniques that worked
- Sleep restriction: compressing time in bed to rebuild sleep pressure
- Stimulus control: reconstructing the bed = sleep association
- Sleep hygiene: temperature, darkness, consistent timing as a non-negotiable base
