Hi LadySlippers,
Thank you. That's very helpful. And yes, I will be following the prep to the letter. I'm very good at following directions. Someone is looking forward to having chicken broth and Jell-O on Sunday.
I was able to talk to a person today who answered all of my detailed questions about what will happen, and I will also be able to ask more questions when I go in Monday morning. So now we all have a step by step explanation of what will happen there. I saw my T today, and my main fear about telling him was that he would say something that would upset me (I mean, he has probably had one, but I don't want to know about it! Or I wouldn't want his opinion about any of this). Then I would be stuck being more upset than I already am. But he was careful and supportive, so that was good.
Now I'm watching videos about it on YouTube, since that seems to be helping someone in here.
