I have NEVER been allergic to anything (except penicillin) in my entire life. Last night I had some canned oysters with crackers and cheese, and within 10 minutes of consuming them, became SO goddamn dizzy, that I couldn't walk to the bathroom, or sit up. I violently vomited for hours, and the headache and abdominal pains were horrible. For the record - that shit is NASTY to puke up. That was about 4 pm yesterday.......outside of the havoc it's wreaking on my bowels today, I'm perfectly fine again. Can one randomly develop allergies at 36?????? Do I now have to be careful eating shellfish? I goddamn LOVE seafood. I'd like to think it was just one bad oyster in the tin......'cause my boys ate them too and they were just fine.
