This is one of the absolutely most frustrating things for me to deal with. Mayo Clinic doesn't even have a great plan for dealing with Autoimmune Fatigue OR Chronic Fatigue, although I agree it might be linked to centralization sensitivity, I think autoimmune fatigue and Chronic Fatigue is much more.
There are NO good treatments but I do take magnesium, CQ10, CBD1:1, ect. but these may or may not help but aren't really a "treatment"
We need MUCH MORE research in this area and it doesn't make money so.... Ugh. Our system is so awful, especially for those of us with rare and autoimmune diseases.
