How many of us have played under the influence of anything besides the air you are breathing??? How do you think it affects your gaming? Do you do so often?
As for myself, I have played while inebriated to varying degrees, medicated (legally), and wired on some some of caffiene (usually to counter meds). More often the last two then the first, as I have stomach issues with most alchohol. Usually don't suffer any adverse effects unless my hands start to shake from the caffiene, can't snipe the side of a barn like that

. Usually don't have any kind of boost on focus or reaction time when I am wired or on my meds. The opposite most times if I have bad day. Nothing like yawning every minute or so to keep you respawning rapidly.
I have known people to set themselves up with Mountain Dew AND Pixie Stix/Spree candy, and then just go nuts online. Honestly scarey how well these oddballs played in some games, and so poorly in others.
How about the rest of you???
