I have an under active thyroid and have done for almost 11 years. My hair still falls out I'm still putting on weight, I have episodes where I just get a bit lost or forget what am supposed to be doing and my mood swings are driving me and my family nuts. My latest blood results were Tsh 0.04, Free t4: 20.2, and total t3: 1.6. My gp wants to reduce my dose of 175mcg but I'm scared i'll feel worse. Help!
