Well, I normally go to bed at about 10 p.m. as I believe there's no point sacrificing sleep for other activities. No matter how important they might seem, the benefits of doing them will not outweigh the harm sleep deprivation will do to my health.

I usually go to bed early (at about 10 p.m.) because in terms of health benefits, one hour of sleep before midnight is known to be worth two hours after midnight.

I'm afraid, I've become a bit of a night owl as of late, so I go to bed at about 2 a.m. as there are always either urgent work-related issues or interesting things to do.

I never manage to go to bed before midnight as there are either urgent work-related issues or interesting things to do.

Oh, no matter what, there's always something that prevents me from going to bed before 1 a.m. Sometimes I meet my friends after work, sometimes I stay in the office until late.

You know, I'm a night owl therefore I never go to bed early. Every time I try to make myself change my sleep schedule and go to sleep earlier, I just end up staring at the ceiling.

Unfortunately, I don't go to bed until 2 p.m. It makes me feel drowsy the next day. I hate it, but I can't change anything.

Recently I've started going to bed as early as at 9 p.m. because I decided to have more sleep.

I'm a night owl to the bone. If I'm asleep before 12 o'clock at night, something is seriously wrong with me. I'm more energetic and productive at nights than in the daytime.

Oh, I guess I'm doomed to be a night owl. It is at night when I turn into a person of indomitable energy. I manage to get lots of stuff done before I retire for the night.
