yeah as above tolerance is the word... but in general i think you'll be fine, maybe half the xanax dose if i were you, and drink slowly so you have some sense for how messed up you're getting... beer not shots... you should have a good night and sleep very soundly, lol. i used to do the same kind of thing all the time when i had a bunch of random pills laying around, except i substituted trees for the blow... always made for a nice weekend night at home.
