I quit 3 years ago, after nearly 20 years of smoking, after reading Allen Carr's book
The Only Way to Stop Smoking Permanently.
I tried to quit several times before - always a cold turkey nightmare, but after reading that book, I quit and it was surprisingly easy.
Best of all: I don't miss it, and if other people do it, it doesn't bother me - it smells a bit, but that's smoke for you. So I haven't turned into the holier-than-thou ex-smoker, a fate I always dreaded.
The book just cons you out of smoking by making you pay attention while you smoke - and you basically realize even the morning/nice-cup-of-tea-and-a-sit-down/after meal/with beer/after sex/or whatever "special cig" that you can't do without is actually no fun at all.
End result: I'm as certain as you can be in this uncertain universe that I won't smoke again.
So try it out - might work for you too - it worked for 4 out of the 5 people I know who read it.
