Depends on my schedule on what I'm doing the next day. Either way I don't think my sleep schedule is so good as I tend to usually get about 4-5 hrs of sleep plus no naps throughout the day.
During weekdays it is usually between 7 to 8 AM. Weekends are from 11 AM to 12 PM.
As for going to bed it's usually about the same time between 2:30 AM to 3:30 AM. I'm a night owl, but I always want to wake up in the morning to have as much time to do work so then I can have more time to goof off.
This week I've been going to sleep around 2am and waking up around 10:30-11. I usually go to bed later, though. Naturally, I function best going to bed early and waking up early. But my work/living situation doesn't allow for that at the moment.
I sleep from 23h to 7h/ 11pm to 7am. I can't change it but I'm quite okay with it, I love doing things in the morning although I wish I could be so active at night as well.
