I am so glad I stumbled upon this forum, I though I was losing my mind! I have successfully been on Wellbutrin for a couple of years now, and the last time I got it refilled the pharmacy gave me the Budeprion. Within a couple of days I noticed that I had difficulty swallowing, was more irritable than usual, wanted to cry all the time and I do not cry, get dizzy, feel very spaced out and cannot concentrate, and have had severe stomach aches and headaches. At first I did not attribute it to the generic form and thought I had the flu or something, but after these symptoms have not gone away for over a month, I am convinced these are side effects from the generic form.
