I've been on Lamictal (200mg) and Wellbutrin SR(150mg) for about 3 weeks now. Here recently I've been experiencing severe headaches (Migraine quality) and also throwing up. I was taking 150mg of Lamictal and 30mg of Lexapro and it quit working. My Dr. had me switch to the Wellbutrin and at first it seemed to be working ok. Now I've been having the above problems. I was wondering if anyone else has had this happen to them?
