"i&#039;ve been taking bupropion 1 pill 150mg once a day for anxiety and depression for a month and it hasn&#039;t really been working. i feel the same way. the first day i felt that it limited my brain somehow, but that was all. and i find myself not being able to sleep at all at night ever since i started taking it. i&#039;ve been sleeping 2-3 hours. maybe i should take a higher dose or change medication."
