I read the book during smoke-breaks!
I bought this book on a Thursday -- by Sunday evening I was ready to smoke my last cigarette. I remember thinking to myself, "I'll never have to put one of these things into my mouth and light it on fire - never again!"
I haven't smoked a cigarette since August 26, 2007. That constant dull headache is gone. My chest feels open. My tongue isn't furry anymore. I feel healthy.
Read this book. You'll stop too.
