The biggest reason of all – Because smoking cigarettes is not actually under your control. Honestly, how many cigarettes a day do you actually enjoy? If you are like most, maybe 4-5 tops. All the others you smoke, you do so almost unconsciously. Smoking cigarettes is more often than not done by your unconscious mind.
It is like driving. When you first learned how to drive you had to consciously think about it, clutch, brake, accelerator, mirrors, changing gears etc. But what do you do now when you drive? You go down the road, eating your lunch, talking on your phone (not that that is a good thing) and playing with the stereo. You drive unconsciously.
When you first started to smoke you did it consciously, you taught yourself to smoke, you were not born a smoker. But now it is something your unconscious mind does automatically, most of the time you don't even know why you are having the dirty thing.
So unless you deal with the individual reasons unique to each person, you will not have any luck in quitting cigarettes long term and that is why our sessions are tailored to the individual.
