I took Geodon and lost a bit of weight on it. It didn't work as good as Abilify does for me but it's a great option for avoiding weight gain. It's supposed to be the best of all the mood stabelizers for that.
Good Luck
I got put on geodon almost 2 weeks ago, I am not sure if it is working for me me but I have actually lost weight since taking it. I was on remeron and that made me gain weight, then he just did change my meds and diagnosed me borderline bipolar. I hope that helps you, I would try it for atleast a month good luck!
