A lot of people on here seem to HATE the generic. I however LOVE IT. I was nervous when i was put on the bupropion because almost everyone on here talked about how bad it was and the side effects were ten time worse than the name brand. I however have not had anything but a good expierence with it. As for the weight loss I'm not sure, as I was also going through and insulin reistance diagnosis, so the odds of me loosing weight without the metformin are kinda slim. As for my moods, WOW. I love it. I went from STRESSED ALL THE TIME and CRYING to "I can so do this, its all going to be ok". I think as long as you watch what you eat you'll be fine. Good Luck!
