I am similar. I found that the later I sleep, the more sleep I need. I attribute that to environmental noise, like my neighbours waking up at 5:50 and walking with little to no regards for everyone below them. However, when I sleep at 23, I am usually up by 4:30, and I am functioning great. When I sleep at 00, I am usually up by 6:30, at 01, it goes to 8:00, and so on. So I decided that I will not use electronic devices after 21:00.
