my main issue here are the adrenals, but going from a FT3 of 3.0 to 3.7 or 4.0 makes the difference. My mood improves along with digestion, I look dryer and I retain less water, my TRT works better, I feel better overall. Also with Lugols, a 1/4 of a grain takes my FT3 to 3.7, half grain to about 4.0. My GF the same way, starting with a FT3 of 3.0, with Lugols on board her FT3 with only half grain gets to 4.0.
I haven't settle yet with the Thyroid, I made a trial couple of months ago to stop taking it, and work on adrenals, and now I just restarted two weeks ago with a 1/4. I'm waiting for my salivary cortisol now, but then likely to go for a half grain again.
I'm currently reading this book, I wish I had read it years ago! I really recommend it anyone who wants to make his or her thyroid working WELL.
