The prep pretty much sucked, but I quite enjoyed the procedure. I was awake and could see the TV screen the doc was watching. It was like Star Trek or 20,000 Leagues Under The Sea. Zooming through vast pink space wastes! Exciting stuff! Started and ended with a hairy a**hole, but otherwise quite interesting. And I got a nice picture suitable for framing, and very complimentary things said about my guts. Very gratifying.
