Just a warning: I'm the same age and lack of adequate sleep came back to bit me hard last semester. (Getting about 4.5-7 hours of sleep every day, working out a lot, school, programming). It took me a long time to recover from some sickness and that required some sleeping - now things are so much easier / faster than before. The difference is incredible in terms of focus and work done. Now I'm getting about 6.5-8.5 hours of sleep, and it's much better. I still need to be better in terms of going to sleep, but going to sleep at 10:30-11:30 and waking up at 6-7 isn't bad at all.
