Going to the castle, huh? That's what they call going in for a hysterectomy on the hystersisters.com website. They say you're going to the castle to become a princess, which is what you should be treated like when you return from the castle. Maybe you would find it useful to stop by the site for some tips. I found it helpful for a couple of things like stuff to and not to bring to the hospital, etc...
I hope you fare well. Be good to yourself when you get back. I'm praying for minimal pain and adequate treatment the pain.
take care,
Ellen
