Huxster, you are correct - T3 only supplementation for someone who's clearly hypothyroid (and Trw is clearly primary hypothyroid if she has Hashi's) will only make them sicker. The body needs T4 - I mean, why would it make something it didn't need? And make more of it than any other thyroid hormone??

People on T3 only will always feel like crap if they are hypothyroid.
