I think cold turkey is the best way to go. I decided to try and quit for the first time last sunday, and so far I haven't had one nor have I wanted to have one. The mints idea works well too, keep some altoids or something tasty in your pocket, and have one everytime you think about having a cigarette. Also, a neat thing to do is take the money you would spend on cigs every week or two, save it up and buy yourself something fun.
It's not easy to do, but it is definitely possible. I'll probably be an irritable ass for the next month or so, but I already feel better health wise and it's only been a few days.
