Being around other smokers was a huge problem for me when I was trying to quit; I don't know if it's the same for you. I had to quit going to bars with my smoker friends for a while (even after smoking was banned indoors). It was tough... I didn't want to lose friends, but it was just easier for me not being around smokers. I had to be like: "New rule: friends can't smoke in my car. New rule: friends can't smoke in my house. New rule: if you wanna hang out, come over to my non-smoking house, because I'm not going to the bar with you." But they were good friends, so they played along and welcomed me back when I was ready. If I had been gigging playing bars a lot with smoking musicians during that time I don't know that I could have quit. As time went by I tried joining back up with smoker my friends again to hit the bars and see live music, and eventually the link between beer+nightlife+cigs was severed! So you might not have to quit beer forever. Anyway, you gotta try lots of things to see what works for you of course. Good luck!
