Personally, I wouldn't go. I am missing a very fun weekend as I type this. Boyfriend, horses, mountains, sigh. And I'm here, alone, sober, trying to get over my pity party, lol. The point is, there is tons and tons of alcohol at this event, and at just over a month sober, I knew I couldn't do it. Or, even if I stayed sober, I'd be obsessing over drinking the whole time. Although I am very sad to have missed this event, I know I made the right decision for my sobriety and I don't regret it. I would regret it very much if I went and I slipped, which was a highly likely possibility, no matter how strong I think I could be.
I did go to a small thanksgiving dinner tonight where there was some low key wine drinking. I had water. It was no problem.
So, think about your decision carefully and do want you think is best for you and your sobriety.
