My friend's situation was more serious although not Addison's or other serious issue. She was essentially disabled by endocrine and other problems-- PTSD, Limbic ADD. She got a rather in-depth adrenal cortex hormone panel.
My situation is minor to moderate. I do okay on just modest doses of pregnenolone, adrenal extract and occasionally a little DHEA.
We both include B & C vitamins and get some adaptogens.
We both got our silver-mercury Amalgam fillings removed and did many months of detox (Cutler). B Haley, former chair of chem dept at U of KY, says a hormone receptor for adrenal related pituitary hormones (ACTH, FSH, etc) holds onto Hg about as well as anything can.
