I have problems sleeping - i rarely get more than 5 hours sleep - but i don't deliberately stay up all the time - it just messes everything up.
I'm a bit the same really, can never sleep. Usually just lie there for at least a couple of hours unable to sleep. It would be pretty rare for me to get more than 6 hours, definitely nowhere near the 8 hours that is supposed to be ideal. Its worrying to have such sleeping problems at a young age.
