I stopped six weeks ago after smoking for some forty years.
I used the nicorettes which helped, but the primary motivation was the $$ ( Canadian!) saved. It wasn't easy for the first couple of weeks and I still would like to light up "just one". So far I have resisted the temptation.
It's a good decision on your part and I wish you all the best.
