For certain types of 'play,' a squeaky-clean colon is a must. When time is short, what's the best way to get a quick and complete flush with the least lingering effects? A normal enema seems to take about an hour from start to 'gastric normalcy', although there can be some need to expel small remnants for a couple of hours after that. If one wanted to be clean and ready for clean play in the shortest time, what's a recommended procedure? Many thanks.
