I did a medical grade ionic foot soak yesterday for it. The water was the blackest it has ever been after this use, and I have been doing them since 2021. Later in the day, I felt cold to my bones and could not warm up, so made some cinnamon tea with lemon and honey. It did the trick. I have an appt. the end of this month to see a naturopathic doctor who may have a homeopathic or herbal remedy for it. I can do kinaesiolgy testing on the options. Thank you for the name dysautonomia.
