"so, i wanted to share this experience, for anyone thinking of trying the mylan generic bupropion. the first three days were really beneficial, the only side effects being a slight headache, muscle pain, and a bit of dizziness. i was happy, energetic, and socially enjoyable. then around days 4-5 where i am now, i feel totally overwhelmed, angry and out of control. i have not experienced this before. my working memory is garbage, and i&#039;m a high functioning college student with a near photographic memory. this is the most terrifying part. insomnia and vivid nightmares set in yesterday. i constantly feel like puking, i have no energy, i can&#039;t talk strait."
