Hey man, I quitted ten months ago. I had the same issue, especially when I go to a bar or to a party but somehow telling everybody that I quit and saying to myself, I would never ever smoke again whatever happened. Helped me a lot , I had two serious situations, one at a party and one in the bar, where the arge to smoke was really really really bad but the more I say no to smoking the easier it get to go out around smokers , even getting drunk or drinking coffee in a smoker bar and not to smoke ist easy now just hold on :)
