I have been on Lithium for almost 7 months....I didn't start taking it till after I stoped breast feeding my baby. I only gained 20 pounds while I was pg with her and as soon as I had her I lost all the weight. I started out at 177 pounds when I started the Meds and now i'm almost 200 pounds and the thing is I have been walking like the doc says and O still gain...plus I'm tired all the time and have really bad headaches. and you just can't do that when you have a four year old and a 9 month old......welcome to the club or bipolar
