Mushroom Poisoning!!

Andi, Jeff, Chris and I went mushroom collecting. Found a bunch of Russula mushrooms, which according to the book are a delicious edible treat.......WRONG!! Only Andi, Jeff and Brenda ate them, Andi ate the most. A few hours later we made a trip to the emergency room, since Andi became violently ill.
While we were at the hospital Jeff became violently ill, he decided not to check in since the doctor told Andi (after conferring with a mycologist and running blood tests) that there was no liver damage. Basically the poison would be eliminated in a few hours. Meanwhile when we called back home to check on Brenda we found out that she was also very sick.
We have three sickies lying in bed recuperating, doctor suggested the BRAT diet, and plenty of liquids.
