Your doctor sounds just wonderful! My son's doctor regularly "made room" for patients when it was needed and it was so appreciated. I know what you mean about being put to sleep but I'll bet if you tell your doctor about this, he could put your mind at ease. There might be something he could give you to help you relax. When I had a colonoscopy a few years back I had the same feeling about being put to sleep but it went so well and whatever they gave me just before really did put me at ease. Hope everything goes just perfect for you on Friday!
