Hi, I have been using nicorette gum 4 mg for the past 2 years and recently started to break out in sweats, nausea at times, abdo pain (after eating), malaise. I feel horrible. I also suffer from diarrhoea at times and have to go to the toilet 3-4times a day. I chew quite a lot, sometimes more than 10 a day, I find it hard to stop. Could it be that I have a stomach ulcer and should I get it checked out? Should I stop drinking wine? I drink about 2-3glasses per day. I am 38years old, active, very healthy before. I am worried
