Been there, done that on most medical tests. This is by no means the worst. In one they had me drink some chalky liquid tracing material. Didn't tell me that I would be dropping stuff that was the color (white) and consistency of concrete for the next two days!!! Saw these white rocks and thought something was seriously wrong. Then, for those of us old enough to remember Welcom Back Kotter, the was the Bronchoscopy - literally "Up Your Nose With a Rubber Hose"!!!
