ive been all over the shop in regards to sleep schedules and ive got to say that waking up when the sun is going down can be... depressing.
ive found that waking in the afternoon is pretty ideal seeing as i have sunlight upon waking and still have some darkness as im going to sleep. i have very nice blockout window coverings, sleep in a west-facing room, use f.lux when i can, work at my own schedule and take classes in the late afternoon/evening, so its pretty sustainable at the moment.
if i had my druthers, id probably run a 26 hour day, but thats beside the point.
speaking as someone that needs minimal human interaction, try the nocturnal schedule if you like, but in my experience it takes a toll.
make sure you have a social outlet of some sort or you could start to spiral...
more to the point: its doubtful that youll find a qt3.14 if youre only awake at night.
