on a serious note: Get you vitamins and try to sleep for full sleep cycles.
for instance - it's better to sleep 6 hours then 7 because in this case you will probably wake up after compliting a full sleep cycle and not in the middle of it. I would even exaggerate and say it is better to sleep for 3 hours than for 7
(A normal human sleep cycle lasts for 90-100 min )


Edit: If you don't sleep right , even a cannon firing by your bad isn't going to help...
