No not me, my fiance. He has all of the same nicotine addictions as a smoker and goes through two tins of "dip" a day. He is getting sores in his mouth and his throat hurts and even though he doesn't swallow the juice, he always has an upset stomach. He is on an antidepressant already so using wellbutrin or something similar isn't an option. We have heard that mega doses of vitamin A help as does drinking lots of water to get past the withdrawal symptoms. Any thoughts?
