The 10-3-2-1-0 Sleep Rule
Gary Brecka's 10-3-2-1-0 rule sets timed cutoffs for caffeine, food, alcohol, work and screens, ending with zero snoozes to protect deep sleep. The strongest evidence backs the caffeine cutoff: controlled research shows caffeine even six hours before bed measurably cuts total sleep time, so the rest are sensible habits to adjust to your own sensitivity.
Last caffeine No coffee, energy drinks or strong tea inside the final 10 hours (adjust to your own sensitivity).
Caffeine has a long half-life; even six hours out it measurably reduces total sleep time.
No more food or alcohol Finish eating and drinking alcohol at least 3 hours before lights out.
Late meals and alcohol fragment sleep and suppress deep and REM stages.
Stop work Close the laptop and end work-related thinking 2 hours out.
Winding down mentally lowers arousal so you fall asleep faster.
Screens off No phones, tablets or TV in the final hour; dim the lights.
Bright, blue-heavy light late suppresses the natural wind-down signal.
0 snoozes Get up on the first alarm. Optional: box breathing (in 4, hold 4, out 4, hold 4) if you struggle to drop off at night.
Snoozing fragments your last sleep cycle and makes waking harder.
Late caffeine, alcohol, blue light and late mental stimulation each disrupt sleep onset or quality; front-loading these cutoffs removes the common blockers to deep sleep.
