Food poisoning ? Ate turkey sandwich at airport. Tasted funny only ate half. Friend ate whole sandwich she is pretty much ok. She got a little sick but seems to be fine. This was10 days ago. I on the other hand, every time I I eat within a few hours I get upper stomach cramping and diarrhea and burping feel nausea but don't throw up . I am ok if I don't eat. If it is food poisoning how long will it last
