So, yeah..I've never been a fan of self help books; Never. I smoked for almost 10 years, just quit for good two months ago. Let me tell you something, Read Allen Carr's "Easy Way To Stop Smoking." I know the title sounds gimmicky, like every other "do something fast and easy"; lose weight, get rich, etc. but do not let the title mislead you.
I really don't know why this book is not more well known. Just google it, you will find nothing but stellar reviews from people who have read it. It really changes your whole mentality on the subject (this is coming from probably the most stubborn person you could ever meet.)
Anyway, I cannot say enough good things about this book, but you really have to read it yourself, and follow his advice (He tells you right off the bat, not to stop smoking while you read the book.) It's been two months for me and I've tried to quit numerous times in the past, this time no withdrawals, no cravings, nothing. From the last cigarette I had, I had absolutely no desire to smoke. I knew right away that I was done for good. No hypnosis, no scare tactics, no trying to frighten you with what will happen if you don't quit.
Anyway, just read it. I have it on the comp if you don't want to pay for it, but don't exactly know the rules about saying things like that here
