I currently take Wellbutrin and have been for about 8 years now. When I was first diagnosed with ADD, I was started on Concerta but my anxiety went through the roof. As I have learned from switching Dr’s is that ADD meds in adults can worsen the anxiety symptoms. I even tried going off but I noticed within 2 weeks my anxiety coming back. Have you looked into taking melatonin? When i get off track and start staying up late I take it about an hour before I want to go to bed and it helps. It usually takes about a week to get back on track.
