I am on Levrothyroxine, 100MIcrograms..I have excessive sweaing aroung my head when I am stressed, or when I am doing normal things like sweeping the floor. Been to Endocribnoligist, who sees nothing wrong, but I also have extreme fatigue. I can sleep 8 or 9 hours and still need more. I cannot lose weight no matter what I eat, and how much exercise I get. Help
