Cheddar-Pickle Sandwich Illness - Pret a Manger, London England

Airport, London, E16 2PB England, United Kingdom

I ate a fancy cheddar and pickle sandwich at London City Airport on February 23 at 6 am and became violently Ill 12 hours later. Fever, shivering, vomiting every 20 minutes for 9 hours until only bile came out. I still feel lingering effects 72 hours later, my body feels like it was hit by a bus. | Symptoms: Nausea, Diarrhea, Vomiting, Fever, Bile
