The problem is that regardless of the time I wake up and how long I’ve slept the night before, I won’t sleep before 2–3 a.m., and I need to sleep at least 8–9 hours to be able to work, well, actually to bring me out of bed.
Regardless of all this, I always feel sleepy and slow in the morning and the early afternoon, and I can’t possibly work as fast as when the sun is going down or at night.

So I still prefer to get out of bed when I want and get the work done in the evening-night when I am at my top. ;)
