When to Stop Drinking Bang Energy Before Bed
With caffeine's median 5-hour half-life, a 16 oz can of Bang Energy (300 mg) needs about 12 h 56 min to fall under 50 mg, the level where most people can fall asleep normally. That puts the last call at 9:00 AM (09:00) for a 10 PM bedtime and 10:00 AM (10:00) for an 11 PM bedtime. Individual half-lives range from roughly 2 to 12 hours, so treat these as a starting point.
