It was suggested to me to avoid all drinking situations for the first year. You don't try to lose wieght by stocking your house full of junk food, and I believe the same goes for drinking. I was attending situations with alcohol, not drinking, but found myself drinking alone later. Its almost like I would be upset that they could handle it and I could not, and drank later because I was upset about it.
I think its just best to surround yourself with a positive apmtosphere that supports your decision to quit drinking - Why have any type of temptation. Watching that person to your right enjoying a beer may lead you to think that you could enjoy just one. Just my thought.
Best of luck to you.
