First, they drew blood, then they fixed up a temporary I.V. They had me take my pants down, and lie on this big machine that looks like a tube. Then they draw you into the tube, and the machine tells you to breathe in, hold your breath for 7 seconds, and then breathe again. Then did this a half dozen times. Then they injected me with IODINE. It feels STRANGE. Then they repeat the tube routine to take pictures, take out the I.V., tell you to get dressed, and you're done. I felt STRANGE for the rest of the day.
