My advice is not to go to the bar for a while.
I'm glad you came through unscathed - so did I the first time, sometimes the second, maybe even the third...but eventually I'd get fed up at being the non drinker and think 'oh one can't hurt'...
Famous last words.
Right now your Addicted Self is probably saying that you won't give up your social life dammit - and noones asking you to.
Just be cautious - maybe change it a little in terms of people places and things for a while?
