I saw the suggestion of using a pencil or pen like a mock cigarette. It reminded me of this comment from above:
Ex-smokers should never carry cigarettes--not from day one of a quit. One reason is for the real risk of smoking it, and the second reason is that as long as a person keeps cigarettes he or she is also keeping a mindset that he or she is a smoker trying not to smoke as opposed to being an ex-smoker. Ex-smokers and never smokers never keep cigarettes--why would they? It serves no purpose to them.
As long as a person feels like a smoker trying not to smoke, he or she is going to have the psychological problems and play the little mind games of a smoker trying not to smoke. When you cross over to the frame of mind that you are not a smoker trying not to smoke but rather you are now an ex-smoker--and that is what you want to be--the psychological benefit can be both powerful and profound.
If you work on proper frame of mind in the beginning, you can feel this difference a minute into your quit and you will prove yourself right as long as you always remember that you are committed to never take another puff!
