... have been on Geodon for my bipolar for 3 months (since October/09) I thought something must have happened to my metabolism due to drug as I gained 70 lbs. I am also on Levothyroxine for my thyroid even tho my tests indicate levels are normal; I was weighed today at over 200 lbs; 24 lbs heavier than I was 3 months ago after stopping seroquel... what is wrong with me? I cannot lose weight despite exercise and lack of eating... did seroquel completely shut down my fat-burning metabolism? Did seroquel mess up my thyroid? Where do I go for answers that my doctor will listen to? Thank you!
