Weasel, I hear your frustration, and something is amiss having Free T3 over the top at 1.5 grains. Here's the thing, if you're hypothyroid, stopping cold turkey isn't the solution. I get it, the RT3 marker looks fine in its ratio to FT3, but that (like TSH) isn't always the smoking barrel for proof.
Free
T4 is only at 12% of reference range, and
FT3 is > 100% (think about it), so your T4 is converting quickly (and even at 1.5 grains, I speculate there's not a huge excess of RT3 conversion, and the deiodination of RT3-to-T2, T1 can process quickly when/if serum levels are normal/stable). However, the FT3 portion is just building, all indications of pooling, which suggests the free active hormone is not getting to the cells. Again, 1.5 grains is moderate, semi-moderate dose, nothing that should be pushing any of your levels over the top (that's just my take, there could be other things I'm not seeing).
Since starting this process, have you seen a steady increase of feeling anxiety, change in BP, heart rate, sleep issues, any observation in body temp? I don't know if we've covered iron, ferritin & the 24 hour cortisol lab in our previous posts with you? As I stated at the top, I don't like the idea of quitting treatment "if" you are hypothyroid and need thyroid meds. At the same time, it's redundant taking NDTs or synthos if all it does is pool and stop short of reaching your cells, and ultimately causes adverse results.
Unlike testosterone treatment, thyroid treatment can be quite tricky, as there's a litany of variables that need to be checked in order for it to work. Testosterone (for the most) gets in, gets metabolized, and beyond protein factors that might effect the amount of free/bio active test, it does its deed. Thyroid hormone ... Well, not quite the same, and there's a whole host of factors that can roadblock it to the cells, not to mention enzyme and protein autoimmune disorders that can cause havoc!
I know this sounds like a parrot, but I think the first step is a good doctor. If you have one that knows the gamut (or is at least open minded and somewhat versed) primary & secondary supporting
thyroid labs, nutrients, electrolytes, antibodies, deiodinase enzyme process (D1,D2,D3), etc., then I would hope he/she explores "WHY" the results are where they're at, and what steps are NEEDED (if any) to make your thyroid treatment successful. It would suck knowing you're only needing some elemental iron support to make this work, or adrenal balance, etc. In the meantime "possibly" taper back, maybe to at least get FT3 down a bit until you get other solutions.
You might have heard of him.
