That's great your doc wants to use clay, it really works to get rid of mercury. I'd just like to mention that your pituitary gland is part of your brain and mercury does damage it. If you do suspect endocrine problems consider the pituitary gland, it is the "master gland" of the endocrine system.

I'm going to rerecommend the multi glandular especially since your adrenals showed up weak on the biofeedback.

Good luck
