While playing online I usually just drink water.

At the casino I will drink energy drinks (unfortunately I am not old enough to drink legally yet)

Weekly homegame either Jamison Whiskey, assorted types of beer (usually fat tire, sierra nevada pale ale or if I am feeling cheap bud light), and if I am really feeling like a cocktail I will go with some caribou lou (151, cocunut rum and pineapple juice).
