I can only add that after a long stressful situation and feeling terrible, with various symptoms (nurabness, twitches, nausea, vomiting, vision problems), the MRAB and DOs couldn't come up with a diagnosis after dozens of tests (MRIs, blood profiles, EEGs, tilt table, etc.). An alternative doc immediately diagnosed as adrenal insufficiency. He prescribed adrenal support vitamin/supplements called Drenamin, Cataplex B, Cytozyme, and told me to use sea salt at every meal. I felt better for about 5 months and then went off the regimen. I am feeling terrible again after 2months. Still not sure about the adrenals- if its legit or quackery (lots of argument on the web)- but I am starting the regimen again.
