DE caused vertigo

Food grade DE caused extraordinary vertigo about 10 years ago that completely went away after a year. Now, 10 years later I had some bug issues again and I sprinkled some DE everywhere in the room. The room was hot and I had a fan on all night, when I woke up I had an extreme vertigo, throwing up and everything, I had to call the ambulance. Samething happened 10 years ago and I didn't make the connection until now. I thought food grade DE was safe, but it sent me to the hospital many times 10 years ago and once last week. When you inhale DE it goes to your lungs and brain just like for bugs. The Chrystals damage the nerves and lungs. So be careful.
