Hang in there-you CAN do it!!!
I smoked for almost 30 years(started senior yr of high school in 1977) and quit December of '06. I was facing mitral valve surgery in Jan. so I knew it had to stop. I just put them down. My only mind trick that worked for me was to wait--just wait a couple minutes before lighting up. The urge would pass and so on and on , until here I am almost 4 years later and have no more urge to smoke!
Good luck to you!
