Hey Sterling, been doing the ultrasound on the vagus nerve (10 mins before bed) for a month. My ANS is pretty fucked up, so I am not able to immediately relax or pass out, but i was able to observe that I was sleeping a bit longer than before. This week I had an intense couple of days at work with a lot of mental activity, and that caused my ANS to spiral to the point of needing to visit my chiro (who said my heartrate and BP seemed high and my neck and sacrum tight during the visit, which she was able to get back down). I've decided to started doing the ultrasound + breathwork protocol to see if that provides a better/stronger solution, but I did want to ask some questions and get any tips/advice from you (or anyone else here) to speed things up (because I gotta work more, can't just keep relaxing). 1) The US-1000 has 3 settings; you recommend doing doing it at low/medium during the opening and closing box breathing sections + the breathholds and moving up to high during the 3 sets of tummo? 2) Do you have another video of the whole protocol? The emily voiceover version is a little distracting, and I'm not a 100% sure but it feels like the video speeds up at points (or the breath count during the tummo is way too fast for me, not sure). 3) I have a lot of diaphragm and lower core (transverse abdominis, obliques, pelvic floor etc) issues. Those muscles have basically switch off, and when I am stressed, I start breathing from my chest, and that causes too much energy to go up to my head and i feel super overstimulated). I am working on this with my trainer in the gym, my chiro, TCM etc but wondering if you have any ultrasound-centric advice on getting my brain to connect to and start using my core fully again, especially under mental activity or stress. (I have started the sacrum ultrasound on alternate days too btw). 4) In this protocol, you put the ultrasound lower down on the front side of the SCM correct? And no movement needed? Any other thoughts or advice welcome. Appreciate you for all of this!
