Well, I dipped Skoal and Copenhagen off and on for years. Started when I was 12 yo playing ball. Decided one day to just quit and I did.. cold turkey.. never had any problems. I didn't dip for about 10 years. Well, I started dipping Skoal again a few years ago and have tried a couple of times to stop and after a couple of weeks couldn't stand it.. I figured since it was so easy for me the first time, this "time" should be just as easy. Boy, was I wrong... both times after a couple of days I was getting headaches, became really irritable and just felt awful.. I know I really need to quit especially now that I have elivated blood pressure and high cohlesterol.. I really do believe that the tobacco companies have played with the chemicals to make it more addictive.. Anyway, I'm there with ya brother and wish you the best of luck....
