Uhhhh... The "prep" is the worst part. I had to deal with the prep WITH half my body as almost dead meat (post stroke which makes my right side less responsive... I'm lucky to be left-handed) but, if anything, I don't envy you.
Oh, I did get a laugh when I had them checking my upper GI as part of the lower GI and I said that I hoped they wouldn't use the same instrument in the wrong order... I didn't want to wake up with an unusual taste.
I hope the result was encouraging...
The real problem for me is that I have to my time with the keyboard and I have to go over what I've already written which makes it harder to write.
