Well,I'm not on the Invega anymore.Seemed too strong for me.Now I'm on Lamictal,Seroquel,Xanax,and Propranolol.I just had my thyroid tested and I'm borderline Hyperthyroid.I have read that either Bipolar can cause Hyperthyroid,Hyperthyroid can cause Bipolar,or it just plain mimics Bipolar disorder.Now I have to make an appt with an endocrinologist to see what to do about this.Has anyone else heard of this before?
