Tuna Toastie Triggers Illness - Pret a Manger, England

55 Bishopsgate, EC2N 3AS England, United Kingdom

I bought a tuna toastie yesterday for lunch. Around 4pm I started to feel nauseous. I was unable to have dinner and went to bed early but woke up around 10pm when I first vomited then at 1am again. And in this morning again. I feel week and have stomach cramps too. | Symptoms: Nausea, Vomiting, Cramps, Weakness
