I find it depends on whats on my mind. Many times I will wake up earlier then I wanted and cannot get back to sleep because I start thinking of things I need/want to get done. Currently I probably get around 6 - 7, 8 would be a good sleep and 4 - 5 hours on a bad night... I wouldn't worry about it too much, even sleeping 9 hours leaves 15 hours for the day.
