Have had it done once.
Taking the laxatives the day before was the worst part for me. They stuff they give you makes you s#$%t your entire intestines in like 20 minutes. Harsh.
I was only there for the 'OK, we'll talk when it's over' part of the procedure.
Supposed to get the test at 40, if OK, not again til 50.
"Using the whole hand there, eh doc?"
