I wanted to let you know that you may be using too much of the DE. I am poor so even getting the $10 over the counter medication can take a couple of weeks and forget about seeing the dr. I am very sensitive to DE. I went against the advise of others and only use a pinch in my coffee in the am. My abdomen also hurts so I also use Rantadine. I like sushi, and I live in a flea infested area of the country, so I need to treat regularly. I usually feel better in a couple of days, but I'll treat myself continually for 5 weeks after that once a month with the DE. It is probably not what a dr would recommend, but I feel more comfortable.
