Why are you even thinking about it? That's what usually gets us in trouble. Thinking. Listening to our false self, ego, AV.. whatever you want to call it. Remember, you are not your thoughts, and you don't need to act on them.
When the urge, or thought to have a drink hits you just shut it down. Now. Do not contemplate it. Just tell yourself it's "not an option" and move on. Once you do this a half dozen times it will stop bugging you.
