I fell asleep on the toilet once, for several hours. My legs fell asleep, actually all the way to my butt. I had to roll off the toilet and seal walk all the way to the bed. I decided I would wait to see if it was permanent when I woke up. When I did wake, I had "pins and needles" so bad that I was in agony; it was up and down both legs. 10 hours later, it started to abate. Which was good because I was about to call an ambulance. Don't fall asleep on the john. YWIA
