Hello, I'm visiting from the UC board. I quit 11 years ago with the help of the patch, and here's some things that helped me:
"Air" smoking. Yeah, like air guitar. When I got that horrible, itch in the pit of the stomach craving, I'd take in a really deep breath, pucker my lips and exhale sloooooooooooowly through the puckered lips. For some reason, it made the physical craving go away.
Every time my mind or mouth started saying "I'd kill for a cigarette," I'd make a conscious shift and say to myself "but I don't smoke any more." Then I got up and exercised. Stationary bike, walking, good old-fashioned calisthenics, whatever. By the time I was sweaty and a little out of breath, the crave was gone. (It also helped keep me from eating.)
I kept no smoking materials in my home or car - no cigs, lighters, ashtrays. That kept me from suddenly realizing I had lit a cigarette without even thinking. Since I'm a lazy person, it also meant that if I wanted to smoke, I had to get ready, get in the care and drive to the store. By the time I finished doing that, the crave would be gone.
I know what works for one person doesn't work for everyone. Good luck with your efforts!
