Paddler:
I dipped Copenhagen early on in life, then quit when I got engaged,and picked it back up again around 1999. Switched to Skoal long cut and went through a can every couple days until May 15, 2010 which is the day I quit cold turkey and haven't had a dip since. No gum, patch or anything else. It seemed like hell at the time, but in hindsight it was a piece of cake compared to quitting beer. I'd recommend cold turkey if you can do it.
