I had to drink the barium during the SBFT test, walk around, and then they would take pictures every 30 minutes. But no, I've never had a "clean-out" process before THAT particular test.
The only intestinal "clean-out-your-intestines" prep I've had to do is the night before a Colonoscopy (I use pills instead of the liquid stuff) and the morning of an Abdominal CT Scan (which was a barium drink - NASTY).
I'd rather be crapping for 24 hours than to drink any of that prep liquid stuff...GAG!
