When I had mine I was in the hospital 5 days and I only got out on the fifth day because I told the doctor is I stayed another night I was going to strangle the next person that woke my up in the middle of the night. Every two hours they had to wake me for something. Guess I was feeling better if I was contemplating mayhem, so they said if I could walk 15 laps of the floor they'd let me go, I practically ran them.
