So, I ordered a plain crab cake with rice and vegetables ?" no sauce, no mayo. Boy, did that crab cake taste good! About midnight I knew why. I woke up with a dry mouth, a terrible thirst and a headache. The next day I felt sore all over, like I'd been in a fight. My hands felt like they had arthritis. Fortunately, since I don't eat food containing MSG very often, the symptoms cleared by the next day. Unfortunately, I attended a reception that evening, and since I had skipped lunch and was hungry, I ate things I shouldn't have, including a peanut sauce I am sure came from a can. That night, the same thing happened, and the next day I was stiff and sore from head to toe.
