I am reducing the dosages of Wellbutrin that I ve been on for over 20 years. My doctor has reduced my dosage from 300 mg daily to 150 mg over the last two months gradually. On May 1, 2017 I started taking 100 mg and 150 mg alternately and am still on this regiment. I m having problems with my stomach more than I did with cutting the dosage in half. I am walking a few miles each week. Is there a reason I feel good for a few hours then I feel as if I m going to vomit. Yesterday I had an episode after eating some soup and crackers where I became clammy, was sweating profusely then had a large release of the bowel. It was as if I had the flu but there is no fever. This morning I still was weak. I m just wondering if these side effects will go away sooner rather than later. Thanks
