I have used smokeless tobacco for 10 years and I have also been diabetic for 11 years. I am 28 years old, 6ft. 2in. tall, 180 lb male. I have been hospitalized only for my diabetes 3 times in the past 2 years with diabetic ketoacidosis. I want to quit chewing tobacco and want to know what happens during detox period? Also, sometimes and more lately, when I put a dip in I get feelings of having to vomit accompanied by a dull stomach pain. Sometimes, I actually do vomit a few times and then after 2 hours I am fine again. It's not all the time, so I haven't brought it up to my doctor.
