After eating out on sunday, i had severe diarrhoea and stomach cramps. i am now eating ok, but stools very loose. is this normal after this?

On the mend?: Depending upon the nature of your food poisoning, particularly if an invasive bacteria was involved, you can experience post-infectious irritability (some use the term post-infectious irritable bowel syndrome). Of course, persistence of symptoms warrants evaluation to rule out other pathology that needs treatment. May also consider: food allergy or previously unsuspected food intolerance here.
