I had sulfur burps yesterday then went to bed then woke up in my own diarrhea what can that mean it's never happened before ?

Gastroenteritis: This could be a viral gastrointestinal tract infection or bout of food poisoning or intolerance to something you ate. Rest. Drink adequate room temperature liquids including flat ginger ale. Eat a bland nongreasy food diet and avoid harsh roughage like salads and vegetables. For relief of diarrhea take peptobismol,kaopectate or imodium. Symptoms gradually resolve over a few days. See doc as needed
