Help me! (TMI)

Ok so I babysat for my sister in law today. I ate a can of Spaghetti O's for lunch. All day (Since ive eaten) i have had (TMI Warning!!) Explosive diarrhea, horrible stomach cramps, and I feel EXTREMELY weak. I can hardly stay away from the toilet. Does anyone know what this is??

**UPDATE**

I woke up this morning, "emptied" myself out, and now I feel a LOT better than last night. Thank you ladies for helping me. I'd never really had stomach issues (well until last year when I was preggers with our first baby!!) Like that. I'm just glad to know what it was!
