Frankly, I don't think I could do this. I've been a nite owl since I was 8 years old and it's quite difficult to change a 21 year habit. I've actually tried before. In college I had a 7:00AM(it was the only time the course was offered) math class that I barely made it through because I was always exhausted. So if it works for you, congratulations, that's awesome. But for me, I'm going to continue to keep the hours my brain likes.
