Amy’s frozen macaroni and cheese I had Amy’s frozen ricemacaroni and cheese for supper. 1 to 2 hours later I started having stomach cramps and then extreme diarrhea and nausea. It was worse than colonoscopy preparation. I broke out in a sweat, lay down and slept or passed out. Woke with another episode. The diarrhea probably lasted about an hour or two. Slept all night after the last episode. This morning I feel groggy and very weak. I am 73.
