"i was given the generic bupropion xl. i started with 150mg for the 1st week and then went to 300mg after that. the first 3 weeks were amazing. my quality of sleep got better. my mind was no longer on overdrive. i had a never ending list of unfinished projects that i was now able to focus and breeze through. it also helped me to stop binge eating. the only negative side effect was that i started getting mild-severe acne but changing my skin care routine helped it. then at week 4, everything went down hill. i was taking bupropion in the morning at 9am and by 11am, i couldn&#039;t keep my eyes opens. i would end up sleeping all day. i feel so tired that i can&#039;t do anything and i can&#039;t focus. it just stopped working."
