When to Stop Drinking Costa Coffee Latte Before Bed
With caffeine's median 5-hour half-life, a Small (Primo) of Costa Coffee Latte (100 mg) needs about 5 h to fall under 50 mg, the level where most people can fall asleep normally. That puts the last call at 5:00 PM (17:00) for a 10 PM bedtime and 6:00 PM (18:00) for an 11 PM bedtime. Individual half-lives range from roughly 2 to 12 hours, so treat these as a starting point.
