question: I was on Wellbutrin XL 150 mg for 6 days and 300 mg for another 6 days to treat depression. Never been on any antidepressants I m 48 yr old healthly male. The 12 day dose made my depression worse elevated my blood pressure gave me insomnia, headaches and cognative impairment. My Dr took me off completely day one I feel terrible. How long can I expect to feel this way and will my brain recover soon?
