You should sleep earlier. I've heard it's healthier for you or something.
How is that late? I go to bed around midnight to 1am every day! If you think thats late then you need to think again and look at all the other posts in this thread...
I dont go to bed too often, I think its cool to be sitting at your computer and you look outside and its pitch black, and after a game of TF2 or something you look outside again and its slowly getting brighter, then you start to hear birds chirping.
