Like me in a way. Whenever I want to sleep I can't (disapproved); and when I should sleep I can't (ability).
I don't think it'll last long though, I've been sleeping around 23 for 3 days now. It doesn't matter if I wake up at 5:30 now, does it? I sleep early so all should be well. Not like I'll be able to sleep long when I have to go to school in 4 weeks. (yes, I have holiday for 4 more weeks xD [been on holidays since 1st of January lololol])
