I smoked for nearly 10 years myself. I used the patch to quit. Worked quite well for me. The thing you must keep in mind is that if you slip up and smoke don't quit quiting! So what, you slipped up, doesn't mean you're not still quitting. Also, the things that helped me quit was constantly telling myself that I wasn't a smoker anymore. When I'd feel tempted I'd just say something like "I'm not a smoker anymore, why would I want to do that?"
No worries! You don't smoke anymore!
Peace and Love,
Stephen
