Great question. Keep chipping away at the local treatment. I’d highly recco Brian MacKenzie’s great course, Art of Breathe. He has an App called STATE as well. This will be the most powerful way into the brain. And it will give some real input into your spine/Cns mechanically. That will be the base of getting ahead of that high tone. If we saw you in person in SF, we’d teach you the same.
