OK, just saw your response.
I think what I was remembering were the discussions between Alex & JeanTX on synthroid vs. armour on the over 40 board. I'm not sure if that's helpful or not, as I see you were in on some of those discussions. Anyway, I ran a match search for synthroid armour & found a bunch of threads.
OT, I wonder what happened with JeanTX. I haven't seen her post in a long time. I really enjoyed her knowledgeable, thoughtful posts. I see Alex at times on one of the other boards.
Too bad she's not here right now.
I notice that indeed I have been super foggy (not lazy, just unable to think), so I just went with the synthroid up to 112. It makes sense to me to not change brands when synthroid has always worked for me. I also just got back my full panel and everything else looked really good - no antithyroid antibodies at all! Yah!
I think it's the fish oil I have been taking (pharma grade) which helped the ATAs.
Let's hope that tsh gets down to 1.
Thanks for your post.
