Dip or chewing tobacco has more nicotine than cigarettes and that is what you are addicted to. That is not the way to stop nicotine, it only changes the delivery mechanism of your drug.
There is absolutely a "habit" element to stopping, i.e. something in your hand, a lighter you mess with, etc, but the problem is nicotine and the best way to get over it is to simply stop using the crap. Patches waste your money and prolong your withdrawal, that is all they are good for.
Cold turkey. Gut it out. In three days, the nicotine will be out of your system. Every day after that, you are fighting a mental game. Try to not take it out on those around you. You can use some accountability and a support group, try one of these if you are serious about stopping:
For Dip/Chew/etc:
KillTheCan.org - A Resource To Quit Dip, Snuff & Chewing Tobacco (no patches / no "easing off", you just stop and suffer for a while with others in the same boat)
For Smokers: try this one, they have a daily roll call (accountability aspect) -
Quit Smoking Message Board
