Had a colonoscopy done last year. The harderst part was not eating for 24 hours, and taking that syrup. At the hospital they just put in an IV, made me comfortable, told me to role onto my side and say night night. Next thing I remember was being in an elevator. I asked if there was a problem? Aren't you going to do the procedure today? Her response was, we did it, you're done, you can go home in two hours. Could have fooled me. Felt normal, started walking around in about twenty minutes, fouty minutes later I walked out of the hospital, and drove myself to the nearest eatery.
