I’ve been pre-diabetic for quite a while and possibly slipped over the top once or twice but I’ve never had any medication. ive had several bouts of vomiting/diarrhea ,always after going to bed feeling fine, then waking up feeling terrible with diarrhea and sometimes accompanied by vomiting. Quite often it’s come after a meal out (with either one or two beers).it lasts for 3-4 hrs and then I’m fine. Advanced practitioner doesn’t think it is diabetes related and more likely an intolerance. Meals I’ve had have been different, different restaurants (different country one time). Has anyone had anything similar ?
