The procedure is easy. You will be so snowed on meds you won't even remember it. It is the prep that is the hard part. It's like drinking bad tasting water from a swimming pool. And it will clean EVERYTHING out of you, and quite possibly anyone within a 1/2 mile of you. I distinctly remember chugging down glass after glass of that stuff , and at a certain point would puke it back up into the sink. However, the drugs for the procedure are excellent! Was whacked out for the rest of the day.(legally)
