"i just started taking wellbutrin xl 300mg recently after being off of it for almost a year. during that year i found myself dropping my kids off at school and coming home and sleeping all day. i stopped taking it because my insurance would no longer cover the brand name. after being on and off of this drug for many years i can tell you there is a huge difference between generic and brand. when i took bupropion i was very short tempered, irritable and my hair started to fall out! this is not listed as a side effect and my doctor and pharmacist also assured me this is not a known side effect. after some research i found many women have hair loss on bupropion. for me its worth the $ to pay for brand name."
