I'm hypo too. One problem with that is your adrenal glands which affect endurance. You can read up on what you can do to strenghthen them, but I am trying just sea salt in the morning and vit c. I have also been taking something called Adreset by Metagenics. One other thing is to check your ferritin level. It is your iron stores. If those are low, your energy will suffer for sure. I have been on iron to get mine up.
