They will give you a radioisotope and take a baseline. Then Put you on the treadmill where they get your heart rate up and give you another.
After you have to go eat bacon and go back into the detector.
And on the colonospy it can't be that bad. Listen to Dave Barry
left Andy's office with some written instructions, and a prescription for a product called ''MoviPrep,'' which comes in a box large enough to hold a microwave oven. I will discuss MoviPrep in detail later; for now suffice it to say that we must never allow it to fall into the hands of America's enemies.I spent the next several days productively sitting around being nervous. Then, on the day before my colonoscopy, I began my preparation. In accordance with my instructions, I didn't eat any solid food that day; all I had was chicken broth, which is basically water, only with less flavor. Then, in the evening, I took the MoviPrep. You mix two packets of powder together in a one-liter plastic jug, then you fill it with lukewarm water. (For those unfamiliar with the metric system, a liter is about 32 gallons.) Then you have to drink the whole jug. 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.
After an action-packed evening, I finally got to sleep. The next morning my wife drove me to the clinic. I was very nervous. Not only was I worried about the procedure, but I had been experiencing occasional return bouts of MoviPrep spurtage. I was thinking, ''What if I spurt on Andy?'' How do you apologize to a friend for something like that? Flowers would not be enough.
