It is something that is defiently
possible.
At current I get quite a lot of sleep
however I've gone through stages of being
awake for more than 100 hours, or getting
around 2 or 3 a night.
It isn't ideal but it's doable.
As silly as it sounds the amount of sleep
you get before midnight actually restores
your body more, so if it's at all possible
I suggest you go to bed early and wake up
early
lol even if thats 11:30 instead of
midnight.
Try to get blocks of sleep, 20 minutes
during lunch, an hour in the afternoon and
morning than night really wont do much for
you ...get all your sleeping done at once.
Things like fruit wake you up and give you
more energy than caffiene so in the
mornings grab an apple over coffee.
Hope some of that is a little useful, oh
and welcome
