i have not taken the time to read all that was posted but i wanted to mention one thing. i have a doctor that has me taking detox tub baths with baking soda and epson salt...the other day on one of my thyroid forums i spoke to a girl who was very sick with lead and mercury overload...but she was saying she discovered that she was getting lead exposure from her long relaxing baths. just a thought. she said it was from theglaze from the tub. interesting!
