I've never had food poisoning but I've had giardia and/or gastroenteritis as well as more serious tummy bugs that have long names many times. Actually every time I travel I have at least one bout sometimes several bouts. Not pleasant expecially when you want to get out and about and are only in a place for a day or two. I tatollay missed Chefchaouen, Morocco because I was laid up by a bug I caught in an hammam in Fez. Oh I did have food poisoning in England from a "freshly squeezed" juice. You don't want to know that story. I had to travel by train all the way back to London the following day!
