I gave up smoking cigarettes 17 years ago. I was sure it was going to kill me. After 12 days I realized that I could do it. Biggest thing that helped is that I was told to never touch a cigarette...ever...because if you don't touch one it can't end up in your mouth. And to have a pack at home in a drawer so when you are out you won't buy any because you have some at home and by the time you get there the craving will be over. I still have that pack in my drawer after 17 years!
