What Happens if You Stop Peeing.

A question posed on Cecil Adams’ Straight Dope:

Early this morning after a night of drinking I woke up and really had to pee. I’m sure you know what I’m talking about. But what happens if I don’t? Is there a long-term health risk if I regularly choose to hold it? If alcohol is thrown into the equation, are there other effects or considerations?
