I quit smoking nearly 30 years ago after watching my uncle and grandfather both waste away and die with emphesyma. Dumping the cigs was a cakewalk compared to quitting snuff.
After all those years of dipping and chewing, and repeatedly trying to quit, I've finally broken the habit. A store by the range started selling Smokey Mountain non-tobacco snuff (cherry, mint and wintergreen are pretty good

). I started taking a dip of that every time I wanted a dip. Just being able to have that dip in the lip got me thru the nicotine withdrawal. It's been 5 months now and I don't even do the Smokey Mountain any more. Still have a twinge of wanting a dip now and then, but it's not that overpowering NEED I used to have.
There is no question that getting off snuff was the hardest thing I've ever done in my life, but I did it. Quit. You'll feel a lot better. and think of how much huntin' stuff you can buy with the money you save!
