When taking a little cynoplus and cynomel after waking up, as I have done in the last three days, I end up feeling anxiety-free for a few hours. The same thing happened to me for a few days after smoking weed, the few times I tried it. No anxiety or tics.
I'm not advocating weed use. I feel shady talking about weed. And it has some bad side effects too in my experience. But yes, I do feel a kind of "high" after taking thyroid, a general pleasant feeling, mentally and physically. More extroverted too, and the surroundings look more interesting. Sort of like an ill-famed marijuana high.
