what are the best meds for Bi-Polar 2 ? I have been on Lithium,Seroquel ,redperadol and have bad side effects such as diarrhea, stomach pains and mental confusions, It seems the medication that helps me is Lorazepam,I don't get bad side effects from it ans it helps me eat, it seems like most doctors are hesitant to proscribe it although it has been very helpful for me.
