Are you telling me that you sleep only 3 hours? Oh, i am better now thanks to a training/research made with the University of Edinburgh. Not very complicated, but changed some of my habits. basically we sleep eratically because we created this habit, working few months on it and change it, we came back to normal, normal being a continuous 8-9 hours sleep, not waking up, starting at the latest 10.30.

I normally get 4 hours in the night and maybe a 30 minute nap after work. One the weekends, I get some more.
