chicken royale Ate a chicken royale with cheese meal. About 40 mins later on the plane I started to feel nauseous. When plane lands 25 mins later I vomit in toilet. In a car to where I was going. I had to stop 2 times where I got out and violently vomited multiple times. Around this time I was having muscles stomach and chest pains coming on. When I arrived at my destination I had diahorrea where I passed remaining solids before passing only water. Ad the night wore on, I felt increasingly physical weak and delirious. I went to the toilet about 5 or 6 more times expelling water and threw up about another 6 times which was only more water by this point. I have woken up today still fatigued and physically weak but I no longer have any of the other symptoms. My mother who was with me had a single bite of the burger. Her symptoms were delayed relative to mine but eventually she was the same. She is still very ill today with stomach pains and restlessness. No more vomiting. I have recovered quicker than she has but for reference, I'm a fit and active 28 year old male and she is 50 years old herself. We hadnt eaten anything else that while day aside from some coffee so we are sure it was that burger.
