Hi, Wicket. Thought I'd start a new topic for you (and give Arcafan's back :) )
No questions are silly/mundane. For me, I obsessed over fear of the bag (the catheter). How to change from leg to overnight and the tubing - fear of introducing bacteria into husb's bladder like toxic shock or something. It turned out to be no big deal - at least for me.
So, as far as waiting during the surgery - will you have family with you? I'm sure that will help, although I'm such a loner, I was "mostly" fine without. I worked on my laptop, read newspapers, took magazines, and a book, just in case. Drank high octane coffee - wrong thing to do - wanted to chatter and pace. Find a really good paperback - one that will allow you to mindlessly read - that's all I ended up doing during the recovery and throughout the night in the hospital (when I should have been working - couldn't concentrate!)
You'll have millions more questions - that's why I landed here, so I could ask and get knowlegeable answers from everyone. So, keep 'em coming!
