Oh, you guys are great!

What I'm taking is not called Armour, since here in Canada desiccated thyroid is made (I believe, at the moment anyway) by Parke-Davis. Since it contains both T3 and T4, it makes sense that the T4-only synthetics didn't help me one bit, if indeed my pituitary gland is not up to par.

And if my doctor wants to lower my dosage again <shudder> to compare TSH, I'm going to ask that we increase it to compare TSH and T4 results after two months. That makes more sense, since my T4 is on the low end!

And if he refuses, I will ask for pituitary gland function tests!

You are both brilliant. Thank you so much. I'll let you know what happens on Thursday.
