Thank you for the response! I have gone more freuently today than I typically do and though the stools arent white they are lighter than usual so I am guessing that is the barium blended in (man, that would probably be gag-inducing if I said it aloud...!).
I will continue to drink plenty of water, watch Larry Sanders until the humorous cynicism washes my worries away and remain positive throughout the weekend. Hopefully these tests will give me some answers or, at the very least, a direction.
Upper GI & Small Bowel Series next week.... Yaaaaay, more cement mixing to come.
I don't think you have anything to worry about. If you don't start seeing the barium in the next couple of days then you should contact your doctor. In the meantime I don't think there is any reason for you to make any laxatives unless you are feeling constipated and dietary and lifestyle changes aren't working.
