When to Stop Drinking Dunkin' Latte Before Bed

With caffeine's median 5-hour half-life, a Medium 14 oz of Dunkin' Latte (166 mg) needs about 8 h 40 min to fall under 50 mg, the level where most people can fall asleep normally. That puts the last call at 1:15 PM (13:15) for a 10 PM bedtime and 2:15 PM (14:15) for an 11 PM bedtime. Individual half-lives range from roughly 2 to 12 hours, so treat these as a starting point.
