My wife hasn't had any kind of nightmares with the riperdol. She has been taking it for a couple of months now. Sure she has an occasional wierd dream, but so does everyone else. A medication I was on would give me some really strange dreams, but not nightmares. I don't know about the mania part, my wife is RARELY manic so I can't be of much help there. I would definatly stick with it for a while though just basing it on the ost alone. Me I could deal with a nightmare every once in a while if I was gonna save that much money.
Hope it works out for you,
