Well for starters you've got all the Muslims and members of the Church of Jesus Christ of Latter Day Saints sometimes know as Mormons. That's two big ole' swathes of people who probably don't drink at all.

My wife asked me to stop drinking while she was pregnant, and I complied. I think it backfired though, because I drank more after she gave birth than I ever did before.
