I wanted some opinions and maybe advice because tomorrow is going to be my first day that I am going off of Latuda And going to start taking Zyprexa which is only 10 mg I am on Prozac every morning and 20 mg and I take Ativan 2 mg a day as needed for anxiety so I'm kind of nervous about taking the Zyprexa and with the weight gain comments I'm saying I don't want to gain any weight is there anything that I can do to prevent the weight gain
