Sorry to learn that you drank Mandosca. It sucks, I know...BTDT! Try to put it behind you and move forward. What's important is that you came back here and posted. 2 months is a great accomplishment. I'm sure that you were beginning to feel the positive affects of being sober again. Remember those feels and work towards regaining them.
Putting sobriety before anything else is what keeps me sober. At 4 months sober, I am still careful about putting myself in a compromising situation, one in which I might say F*** I* and wake up to regret my decision.
I would suggest taking a look at your recovery plan and rethink the tools you are using whenever your AV shows up. You can make this happen...you just need to want it more than anything else!
Hang in there!
