When to Stop Drinking Jolt Cola Before Bed
With caffeine's median 5-hour half-life, a 16 oz can of Jolt Cola (200 mg) needs about 10 h to fall under 50 mg, the level where most people can fall asleep normally. That puts the last call at 12:00 PM (12:00) for a 10 PM bedtime and 1:00 PM (13:00) for an 11 PM bedtime. Individual half-lives range from roughly 2 to 12 hours, so treat these as a starting point.
