I stayed away from bars and such for awhile, now I could care less if somebody is drinking around me. In fact it's more fun watching people get drunk and observing the resulting behavior and being the designated driver. The fact of the matter is nobody really cares if you drink or not I have found. Like Scott stated "bored" is state of mind.
Good luck to you, the only silver bullet I have found is not drinking, having one or two was not in the cards for me.
