Nervous about tomorrow

Not sure if I will be around much for the next few days. I have an ERCP scheduled tomorrow. Wish me luck as I am stressing out about it. I have a tendency to get nervous about things like this. It sounds like a fairly simple procedure, and if it helps me feel better it will really be worth it. I just don't like the idea of being put under. Thanks to all of you for the well wishes, and I will definetly keep you all posted on what they find, if anything!
