A good night of sleep induces its own feeling of well-being, excitement, awesomeness. I swear, I have terrible sleep and when I get an 85+ sleep score I'm a different person.
I have 3 small kids. Sleep is an achievement itself. I only get to experience at most two of "good", "night" and "sleep" :).
(Back before that, in some previous night, my body would still take 8-10 hours of sleep if I let it, and the more I did, the more tired I felt throughout the entire day.)
