Thank you for the link. I've heard about adrenaline dramatically improving performance but at a cost like you said. Maybe I haven't tried Caffeine drinks enough to know but my performance doesn't seem to change much. That article provides a better explanation by what people mean when they say it is a performance booster.
It is an opinion though. Everytime I see a Nintendo game get a low score people run to the review and rage about it. I think that is a little bit immature.
