OK, well, you've now added quite a history to your post! That changes everything. I thought you were new to thyroid hormone replacement.
One thing you should know about doctors, they always want you on levo. It's all they understand. And they don't understand that very well! They do not understand T3! They just cannot get their heads around the fact that the FT4 is always going to be low if you're taking any form of T3, and they fret and fuss and waste time and effort trying to raise it. It doesn't matter! If you are taking T3, the body only hangs on to the T4 if needs, and it doesn't need as much because you are taking T3 ready-made. T4 is a storage hormone.
As for taking you off NDT because your T3 was too high... All the stupid man had to do was reduce your dose. Talk about throwing the baby out with the bath water!
So, it would seem that levo doesn't suit you. Were you well on NDT? If so, I would go back on it, if I were you.
