Today my first bowel movement was fine, next 4 ones in 6 hours are very water no nausea or vomit what to do for now? 4 trips are alot in 6 hours?

Likely food related: Although your frequent bowel movements may be an alarming change from your normal routine, this is unlikely to be a significant concern. It is from likely from eating something that didn't agree with you & should improve in the next 12-24 hours. Recommend staying well hydrated with clear fluids. If you develop fever, significant & persistent abdominal pain, blood in stool, nausea/vomiting, see MD.
