You'll get through this!!! Hopefully your body will learn to deal with the radiation after a bit of time. Rest as much as you need to
Wouldn't do any good, they can't check if the pipes aren't clear, which is why you have to do the uncomfortable prep. The actual process is nothing if you are asleep. They asked me if I wanted to watch, I said "sure". And that is the last thing I remember until they wanted me out of the recovery room bed before my brain unfogged. I guess I'm more "susceptible" to the anesthetic than most.
