Have you heard of Food Grade Diatomaceous Earth?

Always the experimenter to keep my mind off household chores, I bought a big plastic container of this stuff three weeks ago after reading about it on many webpages. I began with one teaspoon so I wouldn’t have any side effects and worked myself up to one tablespoon which I will begin increasing tonight. The only result I’ve noticed so far after three weeks is an increase in energy, motivation and lack of crashing fatigue by 5pm plus a long, deep sleep. I guess this is significant! I’d like to know if anyone else has either heard of it or takes it too and what you’ve experienced.
