I'm not bipolar either, but have my share of issues! My OB prescribed me klononpin (.5mg) and i tried prozac, but it messed me all up. I couldn't sleep or eat for the entire week i was on it. Now i'm on 50mg of Elavil instead of the prozac.
The combo of pregnancy hormones and stress has made me almost rageful. It's really hard keeping everything in check. Talk therapy helps too.
