bowel preparation
"My doctor had me take Suprep the day before the procedure. The first dose was at 7am and the next at 4 pm. No food allowed, just clear liquids and jello. The first dose and water I drank too fast and projectile vomited. Had enough in my system to have it work within ten minutes after. Took second dose at 4 pm and worked within five minutes. Tastes awful but much better than the gallon jugs of other medicine that used to be prescribed years ago. Second dose went a lot better, but if you have a sensitive stomach drink this as slow as you are allowed."
