2004.08.19 Game-Performance Enhancing Substances

With this retro-episode where it had a special segment which talked about "Performance Enhancing Substances" and I don't mean illegal substances. Yeah, I'm talking about caffeinated drinks, sugar-loaded snacks and others. Is it really as bad as the show made it sound.

Any of you 'power' gamers out there, have you tried it and does it really help you game better?
