Was on holiday a few years ago and came down with food poisoning a couple of hours before catching the flight home.

I was vomiting every 30 mins like clockwork. In the taxi to the airport, while queueing at the airport, on the flight, while heading home at the other side. Just awful. I'd never been that ill before or since.

Vomited subsided after the first day but couldn't eat much for a couple of days after otherwise it was back to square one. Was heavily fatigued for about a week after.

I won't say what country I was in or the specific dish I suspect made me ill, but I will say i think it was a chicken casserole-type dish I had 36hrs prior. Its served in a signature pot and the restaurant was busy. Having worked in kitchens in a former life I think they re-used the pot and leftovers from another customer and just topped it off. That or the chicken was bad.
