Yes, I saw the list on Fluoride issues. I'm so glad you posted that link. It's a definite possibility. I need to see what other areas in my life might be introducing it. I don't want to recontaminate myself after getting rid of the years of buildup. Ugh, when I think of those nasty fluoride treatments at the dentist when I was a kid ... it makes me MAD! I think about how much sicker my younger sister is, and she's paranoid about her teeth health so is probably over-exposing herself to fluoride.
