Hey splitimage,
Sorry you had a tough time of it. I was really hoping you would be able to go to the reunion, relax and have a good time. Its hard to have a good time when everybody else is drinking and you are having urges.

When I get out of a situation like that, I really need to connect with my recovering self. I talk with somebody else who is in recovery or write about it or get into some literature. That seems to help me get grounded back into my sobriety.
