Yeah, I also quit smoking I think 7 years ago and I did it just like you're saying, for a few months I stayed away from ALL of my friends (they're all smokers) and after those months I was like "I'm not going to ruin this after those months". I had a slight tendency to keep myself busy with peanuts and candies, not as much an urge to eat as it was a way to keep my hands and mouth busy, but I dodged that bullet cos I was in the middle of playing the hell out of some MMORPG at that point which kept me busy enough to avoid friends and not stuff my face.
