I quit the day before Hunter was put inside me (we were IVF) I just ran out of excuses basically.

Every time I wanted a cigarette I would just visualize myself, in a car with my new born baby, rolling up the windows & lighting up..... blowing the cigarette smoke in my childs face. I figured there was no way I would ever do that (or allow someone else to do it) so how could I possibly keep smoking?

Once I was finally free of 'the demon' I never looked back. I hope that helps.... good luck, I know quitting is a hard thing to do.
