MaryAlicia, I spent 2 1/2 hours on the table a few months back. They will give you a relaxant if you ask them. I didn't need one but most people do for the long scans.
Ask if they have headphones for music. My last one didn't and I just had ear plugs. Ask for a washcloth to put over your face then if you open your eyes, you just see the wash cloth.
I personally didn't take a break because one of the worst problems for me was getting on the table and getting comfy. Did "not" want to do that again and I told him to keep going and just get it done.
They couldn't believe that one.

I will be thinking of you. Just thought I would give you some hints. Oh, I always ask for a light blanket. Just makes me feel more comfy and snuggled.
Hugs
