Bacon Cheeseburger Illness - Whataburger,

I ate a bacon cheeseburger with only bacon, cheese, and ketchup at about 7pm. I woke up at 3 AM drenched in sweat, still sweating, burning up. I had severe cramps, nausea. I barely made it to the bathroom before I vomited, then I had to sit on the toilet while holding a bucket. After two hours the fever broke and I had chills. I thought it was over and was going to go lie down.. it wasnt. It persisted for 12 hours. Never eating there again. | Symptoms: Diarrhea, Nausea, Fever, Vomiting, Cramps, Chills, Sweating
