As a drinker and a gamer, I have mixed the 2 on several occasions but I was wondering if anyone here actually made a drinking game out of tabletop sessions? What rules do you use and when do you stop, because while enjoying the spirits can help loosen everyone up passed a certain point its just detrimental to the game.

I think the point of drinking games is not to stop?  Even if "you" stop, "someone" should keep drinking because that's more fun for you, right?  Only everyone's thinking that.  I've seen people who really like drinking, and those who really like pen and paper RPG's, but I've never seen anyone down a shot at every crit attempt or something.  I'm sure someone has some stories about it, though.
