Deprogramming is part of the process of quitting to smoke. I do now never want to smoke. It is not attractive to me as a way to relax or focus. I can stand in a tobacco section of an airport taxfree shop holding a 5 cartons in my hands with absolutely no desire to smoke. Likewise for being around other people who smoke. There is no creeping need, no urge.
The deprogramming comes last. When it came around for me, it was gradual but it did definitely come. There is no way, not a chance in the world that I would somehow "relapse". It just is not interesting to me any more.
EDIT: *On slaying the dragon*
I want to add the timeframes, which could be useful as anecdotal data.
It took me 9 months after my last cigarette to get rid of the "critical urges". Then after that it took another 12 months to get rid of the sweet itch I would get. After that period it was gone completely, and I mean absolutely completely. It was an exorcism. To anyone trying to quit smoking; know this, if you fight through it, it all does go away.
