Repeat Foodborne Illness Suspected - McDonald's,

Ate at Mcdonalds, with in a hour and a half had extreme stomach pain and cramping followed by several episodes of diarrhea with in a hour or so after it all ended I felt fine. I ate at the same restaurant about 3 weeks ago and had the same thing happen then too. I've got a feeling its the restaurant not me. | Symptoms: Diarrhea, Nausea, Stomach Pain, Cramps
