This is a great place to learn to quit smoking. not so great for people who want to advertise.
Learn is the key word.
Smokers are oblivious to their plight while they are smokers.
I think it must be some form of denial.
Whatever it is, you need to know what you are up against.
It's probably not what you imagine.
Unlearning the psychological connections to the repetitive actions and ritual is the key.
You only do that in time and by making other choices as a non smoker until you see the changes so you can accept the different reality and cope with your emotions in other ways.
