Currently on 10 much of t3 following diagnosis of Hashimotis tho euthyroid. Only possible having gone privately. Main symptoms were depression and anxiety. These improved a bit tho note amon anti deps too. Anyway in recent weeks become exhausted. Comes in waves. I'm ok for a few hours then I feel like I have no power to the extent that I feel I have to make an effort to keep breathing. Got tsh and ft4 tested. The former came back at 0.98 (0.35-5.5) and latter 8.6 (7.86-14.41). Could this explain fatigue? Tested in the morning before taking t3 which I take in two doses of 5mcg st 8am and 3pm. About to see the same endo on nhs. What should I be asking? He had suggested taking st t4/t3 combo. What would that be?
