I too experienced those things and was able to improve the symptoms with magnesium, but then my body just couldn't take any chelation and I went back down again. I had the 4x cortisol saliva test done and it reveled the hypoadrenia.

Different things can cause hypoadrenia or make it worse. I think that I have genetically weak adrenals. Also, candidia and mercury can really be hard on them.

I take nutrients for my adrenals-magnesium, vitamin C and pantothenic acid. I also now take Isocort a natural cortex replacement because my corisol levels are so low.
