I just turned 40 but noticed this thread under the "new posts" search. Forgive the intrusion but I had one done two years ago. The procedure itself was quite pleasant. Here is how mine went:
Dr.: Ok Mr. Hall, we are going to start the procedure now. We are inserting the scope now.
Me: Ouch. But Doc, I can feel everythi....
Me: (next immediate thought) Wow, so this is the recovery area. How long have I been out?
I have no idea how long the procedure took or anything. Lights out.
Now the prep work is brutal. Some people do fine with it. Not me. I was getting examined for bleeding which they thought was from a flared hemarrhoid but wanted to be sure. Going to the pot and wiping every 10 minutes was quite painful. Also I do not think Sprite will ever taste quite as delicious again since they recommended mixing Sprite with the cleaner-outer RX.
