And here's an excerpt... on exactly that topic.
After mixing the jug of 'nucleaer laxitive' and starting to drink it
..."This takes about an hour, because MoviPrep tastes -- and here I am being kind -- like a mixture of goat spit and urinal cleanser, with just a hint of lemon.
The instructions for MoviPrep, clearly written by somebody with a great sense of humor, state that after you drink it, ''a loose watery bowel movement may result.'' This is kind of like saying that after you jump off your roof, you may experience contact with the ground.
MoviPrep is a nuclear laxative. I don't want to be too graphic, here, but: Have you ever seen a space shuttle launch? This is pretty much the MoviPrep experience, with you as the shuttle. There are times when you wish the commode had a seat belt. You spend several hours pretty much confined to the bathroom, spurting violently. You eliminate everything. And then, when you figure you must be totally empty, you have to drink another liter of MoviPrep, at which point, as far as I can tell, your bowels travel into the future and start eliminating food that you have not even eaten yet."...
