Why are you staying overnight in a hospital if you're healthy? The few times I've stayed overnight in a hospital, it was for surgical recovery and I definitely slept. I was on so many painkillers, I barely remember the experience. My wife did a four-day stint in the ICU when her liver failed years back, and from what I remember, she was barely conscious the first few days. I don't know if I'd call either of those experiences comfortable, but she's alive and I now have a working spine, and neither of those would have been true otherwise. So thanks hospitals.
