"All it takes is willpower"...Well, it's true, but it takes a whole heck of a lot of it. The best advice I can give is to find your motivation. Every person who successfully quits has a different motivation. Family, health, money, sex, whatever. Just know that you've got a big beast on your back and there's got to be a bigger drive to get rid of it. I've been quit for 7.5 years now. My motivation was my wife. She was torn up about me being a smoker and I didn't want to do that to her anymore. Cold turkey kicked it and am better for it.

That would just turn this site's front page into pictures of Bill Gates promising $10,000 to each person who upvotes....a downvote has its purpose.

That's actually a pretty wonderful idea. Attach a name to a downvote. People tend to think more when they can't hide behind anonymity.
