Same here. I've been quit for 35 years now. I've gotten to the point where just a hint of cigarette smoke will close up my nasal passages to the point of just barely being able to breathe.
Actually, I carried an open pack of cigarettes in my shirt pocket for 3 weeks after I smoked my last one. Then I put them it in my desk drawer at work for a few weeks after that. I actually found that having them handy was less a temptation than what I had experienced by not having them in previous attempts. But this method may not work for everyone. Another factor that was different also between previous attempts and my last one was that I was finally determined to quit whereas in the failed attempts, I didn't really have my heart in it. Attitude and a real desire to quit are key.
