I can't sleep enough

Hello, yesterday I went to bed at about 20.05. Later I woke up getting a text message and after that I slept again until 01.50. That's not even six hours. I went up at 02.45, after trying to fall asleep again. I want to sleep more, but I just can't. So now I have been up for four hours. I think that my friends in Norway sleep like normal people, 23.00-06.30. I will try to do the same there.
