Yeah, the bowel prep is a pain in the er "caboose", that's for sure. But it is such a wonderful pain knowing that your surgery is just hours away.
I have the same set of dilators. My partner calls them my numchucks because they are so hard and heavy. I can regularly use the first three, but "Big John" as I call the fourth one, is really hard to use and I only occasionally will go through the extra effort to dilate to that size. Also, if you think about it, you'll probably never run into a guy like that.
