I feel a lot like this as well. I have a LOT of reasons to stay quit. My main motivation overall is my children.
However -- what is helping me stay quit... hell, that changes every day. Sometimes several times a day.
If my asshole sister can quit, so can I. Money -- I can save $130.95 a month. Smoker's lips -- gross, right?
I have to sometimes just sit and browse for smoking related illness pics. And YES, there are times when I'm feeling like -- no, I can't fail this. I don't need any jackass all lined up to tell me "I told ya so" -- like as if they are wishing me ill or didn't believe I could quit.
Mostly I just enjoy that I'm free to complain and whine as much as I want and my husband and kids don't care. I spent at least an hour wrestling with 1,500 lights in the Christmas tree last weekend and just grumbled and bitched toward the end -- hubby was like, "Do you want me to finish those?"
"NO! What I WANT is a cigarette, THAT is what I want!"
So my 6 year old daughter comes on over, "Here mama, I brought you a lollipop, I think this will help. And I'm proud of you, mama."
3 year old son comes over and looks up at me. "Lollipop?" -- I take it out of my mouth and hand it to him... he walks off with it.
Hubby brings a new one and a fresh coffee. *sigh*
I got this.
