You pee with beer (and alcohol) cause it suppresses anti-diuretic hormone (ADH). This hormone causes the kidneys to reabsorb water and when it's suppressed they don't do this causing you to pee more. That's why you dehydrate with alcohol.
Hahahaha... No kidding. I was fully hydrated before I started drinking beer that evening. Thanks for the post, but I understand the science. Plus I have a wife , and if you have one too, you'd know that they are going to make damn sure you drink enough water and do whatever else you are supposed to be doing.
