For example, if I had 50mg of caffeine, how much water would I have to drink to counteract the caffeine’s dehydrating effect?
It’s actually Crystal Light Energy I’m concerned about. You mix it with about 17oz of water, and it has 120mg of caffeine. So I’m really asking how much water in addition to the 17oz I’d need to drink in order to break even.
