Hello!!
It is totally normal to be nervous...I only wish I'd found this forum b4 I had mine!!
I totally echo what Elizabeth said, having surgery has given me a lot of improvements too. I think what you see in the posts is people that are still struggling b/c even though we are told that it isn't a cure, we all secretly hope it is (at least I did) so a lot of it is struggling with the disappointment that we are not back to what we are like before. But, that doesn't mean that things didn't improve, for most of us, it improved a lot!! So don't let us scare you off, there are different stages in this process and each one is difficult to deal with.
So...I am sending you all my thoughts and prayers and healing vibes...I know you are going to do great in surgery and recovery and we will be talking to you soon!!
I slept on my side for months, I couldn't stand lying on my incision. A good pillow for your head and one to go behind your back to keep you from rolling over works well. There are some tips on the Health pages too:

It give you a list of stuff to bring and some other tips.
Good luck and please let us know how you are doing!!
