Re:Brighter in the morning? (Score 1)

I don't believe that's the case. Unfortunately I can't cite any references, but I recently heard that "grogginess" when a person wakes hinders ones mental and physical operation as much as going without sleep for 48 hours. For some people this state of grogginess can last up to 2 hours. (I'm pretty sure that's the case for me, heh.)
