bowel preparation
"First time having a coloniscopy and am grateful to have found this site and read such a variety of experiences. I drank two doses of Gavilyte-G, totaling 4 liters after following a prescribed diet. I drank 2 liters starting at 6:30 p.m. one evening and the next 2 liters the next morning starting around 6:30 a.m. My coloniscopy was set for 12:30 p.m. that second day. For both the evening and morning doses, I drank abiut 8 oz every 10 to 15 minutes. For the first dose, it took three hours before the medicine really started to work, but once it did it was very effective. I went to bed around 12:30 a.m. and slept fine without disruption. The morning dose worked immediately. Skin burned at times, but vaseline helped."
