I'm so sad! I just found out I'm allergic to shrimp.
how did you find out what were the symptoms?
I had a weird tingling in my mouth, and ended up with a bad case of diarrhea. 
make sure you drink a lot of water diarrhea can cause dehydration. 
Really? That would have been good to know last night! I had a terrible time getting any sleep.
that sounds awful, make sure you drink a lot of unsweetened fresh fruit juice that will help you
