My most pleasant waking up experiences (in terms of my own body, not who was with me) were when I worked nights, and woke up around 4-4:30 pm.

On a day shift schedule I often feel too warm when I go to bed, and too cold when I wake up. When I worked nights, the cool mornings and the warm afternoons canceled both of those out and felt great.

As such, I only needed 6 hrs sleep when I worked nights. Now I feel groggy unless I get 8.
