I started on the generic brand of wellbutrin about three weeks ago to help stop smoking and help with anxiety. I gave up cigarettes and started working out an hour in the gym to help counteract weight gain from quitting. After the two week mark on the pill I have bloated and broke out in horrendous hives from my neck down. I called my doctor and he said stop taking the pill. It has been two days the scale has gone up six pounds and the hives have not stopped! How long before it will be out of my system? does anyone have any tips on how I can detox?
