I was on 100 mg of Wellbutrin from November 2013-June 2014 for major depression. I then stopped taking it, at the recommendation of my doctor, because my symptoms were gone. I have recently started feeling symptomatic again so my doctor prescribed me 200 mg of Bupropion SR (generic Wellbutrin) taken once daily in the morning. I have experienced the normal side effects of dizziness and headaches however I did not feel those effects when I first started taking the medicine in November 2013. It made me wonder if this was too high a dosage to start with? I asked my doctor but he said these side effects were normal. I just want to be on the safe side because I know the more Wellbutrin you take, the higher the chance of seizures. Plus, I looked at the recommended starting doses and they were lower than 200 mg.
