A person should get enough sleep each day. I need about 7.5 - 8 hours a day. But once I hit 9-10, I become groggy, and sluggish, almost as if I'm in some kind of stasis or coma and my mind can't even think straight.
Get enough sleep and go for at least a 1/2 hour run or swim in the morning to wake yourself up. It really gets the blood rushing and wakes you up.
