It's not an uncommon feeling Nikka - it's normal to have feelings/reminders/urges to do the things we used to do.
You are right though - no one is going to tell you it's OK to drink "just this one time" - we all know that's a total pipe dream. And I think you know it too, right?
It's most likely just your AV playing it's tricks again...don't listen to it. Yes - it's "not fair" that we can't drink with our friends. But at the end of the day life isn't fair. You know exactly what to do though, and coming here to talk it out was a good idea.
