When to Stop Drinking Celsius Essentials Before Bed
With caffeine's median 5-hour half-life, a 16 oz can of Celsius Essentials (270 mg) needs about 12 h 10 min to fall under 50 mg, the level where most people can fall asleep normally. That puts the last call at 9:45 AM (09:45) for a 10 PM bedtime and 10:45 AM (10:45) for an 11 PM bedtime. Individual half-lives range from roughly 2 to 12 hours, so treat these as a starting point.
