Miller light has like 3 carbs, and has some essential amino acids in it. It will dehydrate you less than wine or hard liquor. Arnold used to down a pitcher with his post workout meal. I say, that if working out, and how you look, prevent you from going out and having a few beers for a good time, then you have totaly lost the reason for working out in the first place. I drink once or twice a week, but make sure to stay very hydrated, and stay away from any sugary drinks, except for wine.
