@HunLepto I agree actually, was just pointing out how common it was for those to occur together. The gamers that rely on that stuff are usually marathoning , and are going on for many many hours, far more than would be healthy anyways. And those who are not, usually think it improves the reflexes or some other aspect to their gaming. Then you have the usual group who are just drinking it as a preferance.
Personally, I am none of the above, and don't drink them, or even coffee for that matter (can't stand the taste of coffee, too bitter, despite any additives put in like sugar/creamer). Just good ole natural concentration gets me through a gaming session, and even then I will take breaks and do other things.
