anxiety
"I am on 150 mg of the generic bupropion for approximately 2 months now. The side effects have been increased anxiety and irritability as well as really bad insomnia. Went to see the doctor and they increased it to 300mg a day. I am skeptical, thinking it will intensify the side effects but they are telling me it should decrease them with a higher dose. I went in to change to a different medicine, we'll see what happens. I still don't understand doubling the dose."
