Congratulations I'm pulling for you.
I always remember my uncle. He wasn't a dipper, but he was a three pack a day man. One day he said, "You know even hogs won't touch tobacco." And he quit cold turkey.
Passed a few years ago in his mid nineties. He was still active and in reasonably good health for that age. Died at home. I'm sure the tobacco would have killed him much sooner if he hadn't quit.
But the HOG comment applies to dipping as well as cigs.
