Last night ,Sunday, I had severe diarrhea all night starting after supper. I had to go to the toilet every 15 minutes between the hours of 8:00P.M.-12:00P.M. Than roughly ounce an hour after that. All this was accompanied by tremendous belching of stomack gas. I felt like throwing up but did not. I have not had to go in the past 2 hours and I drank to cups of a hot tea. Could I be over it. I have dental surgery scheduled this afternoon at 2;30 an hours drive away. Should Ibe canceling the appointment.
