You have a better chance at your quit this time because you have the support of others who are in the same boat as you. No one understands our addiction completely unless they've been there. Everyone on this site has been there. Read the blogs, post blogs, and let us get to know you. The more involved you get, the more support you'll get. I started smoking when I was 15 also. This is my fourth and I hope my final quit. It feels great to be a non-smoker. If you give yourself a chance, you'll love the millions of benefits.
