Here's another one I tried a while back with some success. When you decide to quit, it can't be like, "Well, I think I'm gonna quit today." You need to mark it on the calendar and make a big deal of it. Try to taper down before your quit day.
Try reducing the times you dip by one each day until you're down to three a day.
Do three a day for two days.
Then two a day for two days.
Then one a day for two to three days.
If you want to go cold turkey, good luck with that.
Then on your quit day, plan a funeral for your habit. Plan a little speech, curse the evil leaf and all of its vile ways. Damn it to hell. Gather some friends maybe and bury that last can in the back yard with a shovel. (You may want to actually empty the can first if you're a real fiend- you guys know what I mean) Release some doves or fire a gun in the air if you're really badass.
The bigger deal you make out of quitting, the more pressure you'll put on yourself to not re-engage the habit. When you can tie quitting to a particular event, (ie burying the can), you can fall back on that moment when the craving hits you.
