Hey there,
I myself am experienced quitter. I have been non-smoker many times and always relapsed to chain smoking once i smoked single cigarette... There were periods in my life when I wasnt smoking for 2 years and 1 year and half... but as I said i kept relapsing back to it again... This time I decided to quit one more time, its been 5 days and I feel amazing, never even thought about smoking again.
I know there are people who cant stop smoking for even couple days, I would be more than happy to help anyone to quit, please don't hesitate to PM me ;)
