When to Stop Drinking Dunkin' Espresso Before Bed
With caffeine's median 5-hour half-life, a Single shot (approx 2 oz) of Dunkin' Espresso (118 mg) needs about 6 h 12 min to fall under 50 mg, the level where most people can fall asleep normally. That puts the last call at 3:45 PM (15:45) for a 10 PM bedtime and 4:45 PM (16:45) for an 11 PM bedtime. Individual half-lives range from roughly 2 to 12 hours, so treat these as a starting point.
