When I quit smoking cartons of cigarettes were 20 dollars. I used to wake up every morning with a cough and this sort of constant need to clear my throat. I did try to quit many times over the years but when I finally decided to quit and to do it for myself it was easy. I remember feeling the cravings which were quite strong after 15 years of smoking and saying, man i want a cigarette. But i would always reply to myself, it doesnt matter because you aren't going to smoke, reguardless.
That was how i quit. I wanted to. I acknowledged my cravings. I said I won't smoke anyways. Oh yeah, and use a patch.
Getting rid of the car was the same sort of positive affirmation of life that quitting smoking was, it was a longterm view on life that was all about me.
