What do you mean by thyroid in p.1?
Exactly, for me it was the same overnight improvement. It’s insanely frustrating to lose your normal state after that. But at least there’s still some hope it could be easily reversed if you find the right key to this problem.
T3 (cytomel)
I remembered smth else that might also be in favor of your theory. The very first moment in my life when I faced this kind of sexual issues (well, first time of sexual problems at all). I had been on Roa already but with a lesser dose. I faced exactly the same condition I am in now, but it lasted for a week or even less. And it happened right after the day I experienced very high level of arousal. I had very intense sexual desire I wasn’t able to satisfy at that moment(I quarelled with a girl, and later thought it was all caused by this situation). And now i think that could be the trigger that started some trial version of PAS.
