I can't even imagine going to bed at around 9:45pm. It's ingrained in my body that around that time is still early and the world is quiet so I can work peacefully. I usually go to bed around 2am and wake up around 9am. I understand the freshness of working on a new body (morning), but I think the best I can do is 12am. Idk, I think its up to you how you manage your hours and how productive you are. 5am's aren't for everybody.
