"i had major depression and had difficulty concentrating on simple tasks (even with studies). however after taking bupropion i felt the difference: clear mind, better concentration. i started with bupropion 150 sr then increased to 300 xl. soon after i started having hallucination (heard voices), so my psychiatrist prescribed me ziprasidone and lowered bupropion dosage to 150/day. it&#039;s been couple of days since i started taking ziprasidone, seems like i stopped hallucinating. everything went back to a normal life again."
