Hey Veggiescott, great question. I drink pretty regularly after playing hockey and golf (and at concerts, etc) and I find what I drink plays a lot into how I feel. For instance, recently I've cut out almost all beer. The gluten (assume?) in beer plays havoc with me. Mixed drinks seem ok and whiskey even seems to make my movements slightly firmer the next day. All in all a vodka and soda water seems to have the least negative effect, dare I say no negative effect. I rarely drink enough for a concern with dehydration but I'm always aware of the risk. It goes without saying, a j-pouch hangover is the absolute worst!
