I'm appalled by the number of people who perpetuate the myth that giving up smoking is about holding back from doing something you feel compelled to do for the rest of your life.
It can be if you want it to be. I've seen people post about having quit ten or twelve years ago still fancying a cigarette from time to time. I've seen loads more people a few months into their quit wondering how long the "cravings" will last. I've even seen otherwise sane forum members suggesting that quitting is about staying away from smoking the next one (N.O.P.E.).
Many forum "oldies" will pop up from time to time to express their concerns about having dreamt about smoking, or how they felt tempted but managed to overcome the desire. How heroic!
Quitting smoking is basically about taking the decision not to smoke any more. Of course, there is a lot more to it than that, but broken down into Boolean logic, you either do (smoke) or you don't (smoke)
What really cracks me up (pardon the Americanism) is that many people base their non-smoking future on permissibility Duh! You are allowed to smoke! The broader question is whether you want to smoke or not.
Admittedly, some people have a hard time distinguishing between wants / needs and taking responsibility for their own actions, but still...
Quitting is a decision to not smoke, for whatever reasons you feel make sense to you, but p-u-l-e-a-s-e let's get away from the notion that quitting is a life-long chore!
