I would avoid the pubs or any place with booze. I had to learn this the hard way by thinking I could do it, but I ended up relapsing. I have made a point to get my socializing or "out time" done during the day. Sometimes I keep myself so busy during the day running errands, etc. that I am too tired to go out and watching a movie is gratifying. How about an AA meeting? Often times people go out afterwards.
Best wishes!
