Making sure there is enough jack daniels in the house and... No, just the jack.
Hah! I can't play video games buzzed/tipsy/drunk. I get sleepy after a while and dizzy.
That's why you keep drinking. There's a point where you stay buzzed, not blitzed, while having to pee often enough to never be able to get sleepy. I can play for days once I hit that spot, or at least until the alcohol runs out.
