Every swipe is a fresh mini reward and there is no last page, so your brain never hits a natural stopping point. Into bed at 11. Asleep at 1.
A phone next to your bed is a cue. If it's in reach, the urge is in reach. In the kitchen, the cue is gone.
TonightTonight your phone charges outside the bedroom. Kitchen, hallway, anywhere. It goes there 30 minutes before you go to bed. Use a cheap alarm clock to wake up.
Phone bedtime
10:30 PM
No alarm clock? A cheap one works fine, so don't wait. Chimp is making his own too: the Chimp Alarm Clock has an open drop list.
One per challenge. Chimp covers the day, your chain stays.
Chimp covered Day 4. Your chain is safe.
Tomorrow
