Question: how many hours should you get up before work?
Answer: For some lucky few, that's 6 hours. I tend to function better on at least 7–8 hours. I'm guessing maybe you do, too. I realized that if I planned to wake up 2 hours earlier than normal, and I normally sleep 8 hours, I better get to bed 2 hours earlier to keep the status quo and my body functioning properly.
