To be honest, I don't have much for you accept a 'well done' for riding out the craving so effectively.
And the fact that my dad stopped smoking ten years ago, and he still has some moments like you describe where the cigarette 'calls' to him. I think if you've ever beeen an addict of anything, there is probably still that craving that pops up from time to time, although it lessens as time goes on.
