Hey Linda--
Good luck. I was a nervous wreck. Just did a lot of internal pep talks. Also at the point you're at now, I was just ready to get it over with!
My surgery was 8/28, Thursday. Came home Friday -- that was probably the worst day, but totally bearable. Mostly gas. And I'd hit the Lortab (pain killer) bottle as needed. Saturday, I actually drove (minus the pain killer). Very small distance. When people say every day is a little better, it's so true. By the time the Labor Day weekend was over and I went back to work Tuesday, I felt almost like myself again. Did 20 minutes on a treadmill that day!
Good luck Monday.
