I take (or used to take!) Armour thyroid. It's not available these days, hope it will be again. I'm wondering if anyone else has found a substitute for it? There are few thyroid meds out there that contain T3 AND T4. According to what I've read, people with fibro often have trouble converting the T4 into T3, so a med with only T4 won't help. My doctor is looking for a substitute for me and several other of her patients who take it. She hopes to have an answer by this week. Good thing, because by the middle of next week I will have no more thyroid pills.
