He doesn't use scare tactics, says they don't work. He tells you not to nag current smokers, it's not helpful.
His book works like deprogramming/hypnotic suggestion. He addresses your concerns in a well thought out manner. He addresses all the concerns that smokers have.
I read the book several times, watched the movie a few times, and I became convinced I was now a non-smoker.
You don't stop smoking when you open the book, all that's needed is a desire to stop. As he says, you have nothing to lose. You'll either want to stop at the end, or you won't. Lol, and it's a very entertaining read.
Well, the full movie is back up on youtube. That alone can be enough for anyone. See if you can spot which Game of Thrones star has a prominent part in it. He's good in his roles, he doesn't reek. lol
