Update — three weeks into the diet and supplement plan advised by my naturopathic MD/dermatologist.
Die-off symptoms are calming down. Much less joint and muscle pain, and less intense headaches, although they still come on in the afternoon.
I do credit the Thisilyn and Molybdenum with directly impacting the symptoms — or should I rephrase that: with helping my liver better manage the waste products from the dying yeast.
And even my MD/derm confirmed today that those two supplement additions were good choices.
Thanks to those who pointed me in a good direction (Able, Raster, Missiello, others)! Love this forum!
