@Athene*, a couple remote possibilities come to mind: the glycine can increase growth hormone, and there may have been gluten or an intolerable filler in all the other magnesium preparations you've tried. Dr. Klenner used high doses of glycine in his protocol for MS which also worked for other neurological diseases. Have you tried glycine alone and had similar good effects? I'd be concerned about trying too much of anything until your endocrine status gets sorted out - I'd hate to find something caused an adrenal crisis if you're halfway to developing Addison's. If you're ok with sharing, I'd love to seet your adrenal lab values, if you've had adrenal cortex antibodies and an ACTH stim.
