Gor symptoms and conditions

I have been taking this Welbutrin XL for 2 months. After 4 - 5 days of it, I get nauseus, dizzy and begin dehydration. After being off the medication a couple of days, I feel fine. This last episode, I was in the bed for 4 days napping several times a day and sleeping all night, no appetite, urine became thick and dark. All the while I was forcing fluids, drank Pedialyte to replace electrolytes, and stopped the Welbutrin XL. Didn't whether to go to the ER or try to get to the doctor. Finally gor enough strength to make it to the doctor. Blood tests showed I had come UP to being mildly dehydrated. I'm not taking any more Welbutrin XL.
