"i find risperidone(2mg at night) very agreeable and experience no side effects at all. i hve been on many meds for bipolar and experienced drowsiness and fogginess on most of them but with risperidone its almost as if i am taking nothing at all. there might be some slight weight gain but i started gaining weight when i was previously on chlorpromazine so i cant be sure. i am also on 500mg lithium, half in the morning and half at night. have been taking resperidone for the past 6 months and i hope it prevents relapse which i have been having almost every two years in the past."
