I'm sorry you're dealing with mecury poisoning,althought I'm not that familiar with it, I know that's a difficult one...
The large dose I took was because, when I read somewhere the doses for children, and for animals (which was by body weight), I figured 1 Tb per day for adults was a rather conservative dosage anyway.
But, I should have built up to it.
The die off was bad, but I understand it, and realize that it means that DE IS working.
Besides that, I had results with para cleansing from DE, and I have thried a variety of different things, from Hulda Clark
's recipe(works well up to a point), to Barefoot Dewormer (useless, for me), Bentonite& Psyllium, Liver Flushes, different herbal formulas, and right before DE, I used Oxypowder
Not going into the gruesome details :), I saw results with DE: it works.
I'm going to continue with it, the 1Tb per night for now. I sense my body is assimilating food better and I my energy is way up.
