I stopped last year by using a drug called Champix. It was made available on prescription through the smoking cessation clinic. It works by stopping the craving. You start off in week one smoking normally and taking the tablets and invariaby think this is nonsense for the first four or five days. Then you notice that you are smoking fewer cigarettes and this is because you are not getting anything out of smoking them. In the 2nd week you stop smoking and, to my surprise, I didn't feel any need to have one. You keep this up for another 11 weeks. When you stop taking the drugs you just carry on not smoking. I was aware that I would enjoy a cigarette and all the habitual side of smoking, having a cigarette after a meal and so on, are still there to begin with, but there is nothing there to pull you towards having one. You need just enough will power to say, 'best not have one', there is none of that panic or hunger for a cig. You've probably got several dozen trigger points from habit for thinking of a cigarette but one by one they disappear, usually after two or three times of not having one. You sort of miss it a little bit but there is none of that inner turmoil or anxiety. Eventually all those trigger points disappear and you stop thinking about smoking altogether.
