Meh. I don't really buy into this biphasic hype. If I go to sleep in the afternoon, my body still wants several hours sleep and I'll wake up groggy, disoriented and more tired than before.
I can live on 6, and feel bad. 8 is good. 9 is better. 10 is common for me at weekends when I have no particular plans.
