i ve been taking Wellbutrin SR for probably 12-15 yrs. I ve weaned off it a couple of times, but don t do well w/o it. I ve taken 400 mg a day for most of that time. I was off of it for about 6 wks. I had my check up previous to starting to take it again. My Dr. wrote the script for 200 mg, when I said I thought it was 400 a day she said she didn t think I d been on 400 because that would be too much. When I double checked with the pharmacy, they confirmed I d been on the 400 ml all along. She changed the script, but now I m worried. Is 400 mg a day a dangerous amount?
