I didn't drink for a long time because alcohol did not mix well with my medications. You'd be surprised how upset people can get when you tell them you don't drink. I don't know why it seems to offend people sometimes. But I just got really sick if I drank at all. It was really frustrating having to explain over and over why I wasn't drinking at a party, because people WILL demand to know and act like you are some kind of crazy person.
