I am so leery of adrenal fatigue...
You can do so much messing up by taking things you don't need... You really need a good endo to know if you have a true endocrine issue.
Adrenals simply do not get tired. They are built, like the rest of your glands, to last a lifetime. Only disease or removal can stop it so you need to demonstrate disease. One test cannot accurately show that as adrenals are naturally variable. It takes a few tests and some supporting tests... And then a lifetime of replacements. Adrenals do not rest. They suppress. Some will wake after suppression, some will not, some will go bonkers and you can become Cushing's.
Something is probable wrong... But it seems like even you know this is not the right track for you... Perhaps another opinion?
