I had a big country breakfast with bacon and gravy this morning around 9am. Then around 1030am I began having extreme stomach cramps and nausea. Shortly after I began to dry heave and have severe diarrhea. The diarrhea and cramps continued until around 7pm along with nausea on and off. It was the only thing I had eaten since 7pm the night before. Pretty sure it must have been the gravy because no one else in my group ate gravy and no one else got sick.
