I ate a roast beef hoggie with Mike's way(lettuce, tomato, onions, oil/vinegar, cheese). I told my husband that part of it tasted sour. The next day the diarrhea, stomachs cramps, headache, nausea and weakness started. I had it for 3 days, it seemed to be ebbing for about 24 hours but it has started back. Its been over 5 days of this sickness.
