You can get through those situations, GC. Try to imagine yourself in those situations ahead of time and without a drink in your hand.
You can always imagine us there, too - your SR buddies - our names and avatars guiding you away from the bar. You can imagine me holding my umbrella over the wine glass by your plate and having wine spill all over the table like raindrops when the waiter tries to fill your glass - that would be entertaining.
Preoare your mind and heart; you can do it, GC.
