It is not known exactly what caused the 27-year-old British singer to suddenly feel so ill, although her unease became so bad that she decided she needed professional help. "Amy is in the clinic being treated for food poisoning,” a source told British newspaper The Sun. "She hasn't said what she's eaten but has been telling patients that she feels dog rough."
Amy, you're Jewish. Keep to a kosher menu. I can't say it's perfect but it's your best chance to keep from food poisoning.
