🎯 The Goal: Running on 5 hours of sleep cuts your focus, memory, and impulse control roughly as much as being legally drunk—and you can't 'catch up' on weekends; that just makes Monday worse. The fix isn't willpower at bedtime; it's controlling light and timing in the morning.
☀️ Step 1: Anchor your wake time, not your bedtime. Pick ONE wake-up time (yes, weekends too) and get 10 minutes of outdoor daylight within 30 minutes of waking—no sunglasses. Morning light is the master switch that programs your brain to feel sleepy 14-16 hours later. This single habit does 80% of the work.
☕ Step 2: Set a caffeine curfew 10 hours before bed. Caffeine has a 5-6 hour half-life, so a 4pm cold brew is still 25% active in your system at midnight. Target bedtime 11pm? Last caffeine by 1pm. Swap the afternoon coffee for a 10-minute walk—it boosts alertness without wrecking tonight's sleep.
📱 Step 3: Build a 'landing strip' hour. The hour before bed: lights dim, phone charging across the room (buy a $10 alarm clock), room cool at 65-68°F. If you can't sleep after 20 minutes, get up and read something boring in dim light—lying awake in bed trains your brain that bed = stress.
📋 The 7-Day Reset Protocol: Days 1-2: lock your wake time + 10 min of morning light. Days 3-4: add the caffeine curfew (10 hours before bed). Days 5-6: add the landing-strip hour and move the phone across the room. Day 7: shift bedtime 15 minutes earlier. Track one metric only: 'Did I get morning light? Y/N'. Repeat weekly until you wake up before the alarm.
