I'm sorry about contributing to topic drift with the statistics argument.

As for the drinking thing, the comment I've head here that personally works for me the best (but I'm in no way suggesting this should work for other people here)is that this is one of those things you can control that MAY make a difference. There's so much you can't control about what happens, beyond getting aggressive treatment to begin with, that for those of us who are control freaks, this is soemthing we can feel like we're "doing".
