Doris,

I was unfamiliar with the term HERX, but after looking it up, it sounds like you have more toxins floating around than your detox organs (liver, kidneys, colon) can handle. You might want to get Cutler's book to see if you could take some things to help with your detox phase 1 or 2. My phase 1 was too fast for my phase 2, so I became very chemcial sensitive. I take niacinimide for that now.

Magnesium is key in detoxing.

Also, I had trouble being able to take enough magnesium of any form (got diarrhea) so I tried IVs for a while and that worked fairly well, but was VERY expensive and I felt the way that you described on the day of the IV.

So I now take ionized magnesium (cellular ready-bypasses the digestive system) that I get from mag-i-cal.com.
