Mine was from a döner sandwich. I literally was vomiting while I was taking diarrhea shits. I spent two days on the toilet. Cold sweats, fever, and an overall complete mess. Probably the worst I ever felt in my life. I thought I was gonna die. That was two years ago or so and I still can't even look at it or stand the smell. Ruined it forever for me, even though I used to love it. Share your gross stories!
