I used to get IBS D every day after first big meal every day. A big enough pain! Then I went to Mexico and the last night I was there, I got food poisoning (bad stomach cramps and D all night)after eating an awful buffet at a 5 star hotel.Ever since then ( it's been quite a while) IBS D has been much worse. I will even have to run to the bathroom after dinner every night many times and that never happened before! What do you think?
