Update: holy sh_t! I had a meeting with my boss this morning over skype that I totally forgot about. It was at 8:30. I miraculously work up at 8:29 with no alarm! Sooo lucky! (My phone pops up a calendar reminder10 mins before every meeting, and well, I always check my phone first when I wake up.)

Unfortunately, I had bedhead. But I guess it's better than waking up after 8:30.
