Lol, glad you're on top of all that. I'm not trying to be intrusive, it just would have been really helpful if decades ago when I knew I had stupid 2 setting sweat glands, I also knew about everything else that usually comes with it.
I have found that meditation, breathing, and yoga give me more conscious control over parts of my unconscious nervous system than most people are usually allowed. It helps with the erratic responses. It's like whoever was supposed to be in control of things ain't there, but I can be there if I remember and work it myself. That helps with the crummy digestive system, temperature responses, lack of feedback, and runaway emotional states.
It can be exhausting, like working a complex control panel you have to pay complete attention to, but it's a great tool to have.🧡
