Oh, for tomsteve, I DID have the barium drink. I think it was plain vanilla, it wasn't unpleasant tasting but not especially memorable/identifiable. I just liked the fact that all it made me do is glow in the dark--the last time they made me drink something was for the colonoscopy a couple of years ago, and the results of that were YUCK, to say the least.
The scan wasn't bad, and my doctor said he'd call with the results when he gets them later today.
