I like to get drinks for people I am playing poker against rather than drink myself. I usually drive to poker events to have an excuse not to drink, not that I am a big drinker anyways.
The worst thing that happened to me was one time after a party I came home and had a few more drinks, played online (at a higher stake than normal of course) and won. Then of course come the overconfidence tilt, and then I had the impression that not only can I play poker drunk, I play great poker drunk. Of course when I tried to replicate the results, I lost it all. Or maybe I lost it all because I wasn't drunk enough?
Hell now that I think of it, the best time I placed in my local freeze-out, I was drunk. I gotta finish this post before I talk myself into drinking more when I play.
