@lelia I would fly but with spontaneous diarrhea, I'm afraid I might have to monopolize the bathroom for the whole time of the flight. I don't think the airline would allow me to do it. I know that driving could also present problems because if I don't have diarrhea I have bloating, distention, flatulence, and abdominal pain. In a vehicle, I could lay down in the back seat. I do have an appointment for April 29th. My daughter will be getting home from a trip to Missouri on the 27th. I might have to ask my son or another daughter. How long were you there for testing? Someone said to plan on at least 3 days. Thanks again for the valuable information. You have been an inspiration to me. I'll let you know how it goes. Bless you.
