Haha yep.. I can't take anykind of penicilin or derivitaves or anythign like that. I even found out that I can't come in contact with that shit, while working at a pet store, we had to give these animals this stuff called bactrin which i guess is a penicllin derivitave for animals, and a rat spit it all over my arm, and i broke out in crazy mad hives >.<
Definitly sucks when you get sick though.
