Re: switching to t4 only med?
Maybe you could go on T4 and add T3. I had the same problems as you, but worse my teeth felt like they were going to fall out. My endocrinologist said that the T4:T3 combination of Armour is not good for everyone. So, you might benefit from T4 (Synthroid, Levothroid, or Levoxyl) and then add a little bit of Cytomel (the T3). Unfortunately, I wish I could say that I've found the miracle combination, but I haven't. I think part of the problem is that my Hashi's messes with the output my own thyroid gives and so I'm just not stable.
