I had to laugh at this thread because of my experience.
The damn procedure was scheduled for 7am and I was at the doctor's office around 6, which meant I was up early, so...
I lay on the gurney and asked the nurse, "Is that it?" pointing to the gigantic garden-hose like thing with FOOT MARKS on it! She laughed and said, Yes.
Mind you, I am a 'virgin' back there (well, practically) so I just sighed and thought the worst.
The doctor comes in, turns me on my side, starts the IV to 'relax me' and he said, "OK, I'm going to insert my finger in your rectum now."
The next thing I knew, the nurse was shaking my shoulder saying, "Wake up, now. It's time to go home." I had gotten the rest of my night's sleep!
On the one hand, I was disappointed I didn't see the procedure. On the other, well, no discomfort!"
A friend picked me up and we went to IHOP and I promise you, that coffee and those pancakes tasted SO GOOD since I hadn't had any food in, well, days??
Seriously, when it's time to get it done, get it done.
