I guess I'm the only person in the world who smoked for 15 years, and stopped on a beautiful day, without suffering. I still smoke very occasionally, socially, once a month maybe, but I definitely stopped having daily cravings to smoke alone days after I stopped.
Not quite the same, but I smoked every time I drank for two years, and then just stopped for no reason. Never had a craving, I just "felt like" having a smoke for two years, and then didn't anymore.
This was during the time when you could go to a bar or club in Florida, show some person with a giant bag your ID, and receive two packs of cigarettes, free. I did this multiple times a week, so I always had a huge stack of free cigarettes and bar matches. That was also how I learned you could make friends by always having either a free cigarette or a lighter.
