dpaz, I wonder if you took some strong pain killer like Lortab or Vicodin about a half hour before would help. They are great for pain and they also knock me out! Did they give you a support under your knees so you weren't laying completely flat? You could also ask your doctor if you could take something like Lortab AND xanax or valium. Don't know about mixing the two, but doc or pharmacist would know.
