They are microscopic sea creatures, called diatoms. I think they are a type of hard shelled algae.

I guess an allergy would be possible, but you could just have some serious parasites.

I would try a parasite cleanse with some herbs, or see how you react to bentonite clay.

I know what you mean Sean, some things really just make me feel terrible and I gotta work too, but many of my friends take bigger dosages of D. Earth (up to a tablespoon a day) and they always come back asking me for more.

The main things that still affect me strongly are D. Earth, Clay, and hard work. I feel so over-stimulated after doing some heavy work and just feel really wierd and hyper, with a racing mind. I've recently started taking 30mg ALA after doing heavy work and again 3 hours later, and that seems to help protect me from the mercury that is released from the stress.
