The Allen Carr book worked a treat for me.
I say it worked a treat, I still smoke 15 a day, but when I really wanted to quit, for six weeks it was a breeze. I suppose that gives you a decent headstart, particularly if you've got better willpower than me.
It's all in the mind, man. And the fewer you smoke, the more you idolise the cigarettes you do smoke, which in terms of quitting is counterproductive.
Most interestingly, the physicality of nicotine pangs are mild, you just amplify them in your head. I mean, they don't wake you up during the night do they?
