Hi, my big thing for you to do is to log onto the Iodine side of this forum and ask them this same thing, they are great over there.
Do you have mold in your home or work place?
A lot of CEBV people are purely mold ill and they never get cured as its quite an illness. Do certain places make you worse than other (if its mold all your clothes are contaminated anyways, but still some places are better than others).
Did they tell you you have Chronic-Fatigue-Syndrome first... my situation was mold the random off balance was very often, the brain fog is in all of the mold ill,as well as many many other symptoms.
I actually am recovering though!!!! Iodine, Borax, Colloidal Silver Im taking them all now. My situation may be different than yours but it will only help to check that side out.
