My solution was freezy pops. Every time I craved a cig, I cut open a freezy pop. After about a month I realized I was no longer substituting, but flat out craving that iced sugar water goodness.
I'm over 2 years now smoke free. I've waned down my freezy-pop use but still keep a box in the freezer. Though I'd throw this out there in case it could help anybody else.

Mine was just to plan to quit for 180 days. I had quit for 90 days many times but couldn't seem to make it beyond. So I set 180 days and bought a Batman calendar to make the days. I got a certain satisfaction from marking each day in the Batman calendar. Until somewhere past 180, I just forgot to make it anymore.
