My mother and I went to a hypnotist.... I know it sounds stupid, but it worked! I have been smoke free since April 2006. I can't tell you weather I was hypnotized or not, but I made the decision to quit. That is the biggest thing, no one can tell you to do it you have to want to. I think the hypnotist was just a starting point. My mom has been smoke free too, even though my dad still smokes. I did gain a little bit of weight at first but now I am back down to my original size. I am jogging and excercising more, and everythign smells and tastes so much better.
You make the decision to be healthy, and to be smoke free. Once you have made the decision stick to it. Try to get a buddy to quit with you. That helped me a lot.
