2 years for me so far, quit smokin and chewin!! I used to rotate , chew for a year, and give the lungs a rest, smoke for a year and let the gums settle back down. That was all fine and dandy in my teens and twenties.......but in your 30's ya start to fall apart and become paranoid and a little less "immortal"!! So i quit out of fear lol. Got sick of scrapin white stuff off my gums and hackin every morning. Cant say i still dont crave it once in a while, but its pretty easy to not give in..... especially the more time ya get under your belt. Fishin and golfin are wheni miss the chewin the most, after a meal and a few beers is the hardest time to resist wanting a smoke again.
PS: Hey Pikeguy, how come your dog always looks so guilty lol.
