Sack time tonight
10:00 PM
Right now
11h 31m until: last coffee or energy drink.
Mac and Sham walk-back
Last coffee or energy drink
2:00 PM
Cut caffeine 8 hours before sack time — the half-life outruns you.
Last big meal
7:00 PM
Heavy chow after this hits your gut, not your recovery.
Last big water
8:30 PM
Sip only after this — otherwise you're up at 3 am on the DOT lot.
Screens off, cab dark
9:30 PM
Phone down. Curtain drawn. Sleep temp dropped.
Caffeine has a 5 to 6 hour half-life. A 2 pm energy drink is still in your system at 10 pm. That's why the miles feel short but the sleep isn't.
