It's all in your mind, if you're not ready to quit, you won't.
^^^^This says it all. I smoked for about 45 years and tried to quit several times with no success, until I made up my mind to do it. I have been free of cigs for 10 years now and quit cold turkey when I decided in my mind to do it. I tapered off over a couple of weeks then quit and haven't looked backed. Do I still want one, yes. Do I like the smell of someone else smoking yes. Do I inhale second hand smoke, when ever I can. Good luck.
