Hi! All three of my children are currently going through chelation (they are not autistic, but our local gas company spilled mercury in our home). They have been chelating since the end of Feb. The results have been more sporadic than I thought. Some of the metals were elevated, then they dropped, and then they became elevated again. Is this normal???? Also, we have seen only a little mercury come out. Does mercury come out with the other heavy metals or after the other heavy metals have decreased?
