The last stick I smoke was 13 years ago. Never looked back then and never taken a smoke again despite being in the social environment.
Understand that there is always a trigger before the action. Remove the trigger and association and you will succeed.
When you smoke how does it make you feel? Feel good, comfortable, stress reliever. We all chase the outcome not the act itself. All we need to do is to associate smoking strongly to something you despise, that make you sick to the stomach. This will replace the current association of pleasure. Once you have reinforce the new association, you will be not intrested to look at another stick.
To assist you to do that try to look for someone who is trained in the field of NLP (Neuro Linguistic Programming). Since I am a practioner myself so I knew the technique to make the transition.
It worked for me and perhaps it may help you too. Dont discard the power of the mind, it can create instant change.
I can't remove my triggers, so I need to learn to work through them. Since NLP is your area, what are your thoughts on Allen Car? I read his quit smoking book years ago, but really didn't get much out of it.
I am trained by Dr William Horton from NFNLP. Different person required different approach in tackling their concern. If one does not work try another. The fastest is try to link smoking to something that will make your skin crawl or obnoxious. Remember the scientific study on Pavlov dogs. it works the same way.
