Thanks Stacie! Our problem is

that her stomach is NOT stable since she got sick first time 15 months ago. Also, how and where is it possible to test her for actual levels of Hg before starting anything, and consult with some MD who is an expert in this issue?
Sorry for asking so many questions - i always err on the side of caution, especially since everybody in the family (including my girl herself) are quite skeptical about this theory.
