where is the time?

is there any way anybody can survive without sleep? i have so much to do and not much time left to do everything.
i've been trying all sort of ways to keep awake trying to study. i can't afford to flunk anymore. i've invested too much time and i'm getting very tired of doing it now. i have to finish up the course. i need to do something else before i go insane.
if i were to go for a total health check-up, i'm sure i'll fail. the stress hormones must be having a party in my body. i've been craving for all the comfort food. i actually asked for something i've not eaten in a long time yesterday. something i've not seen in the freezer at home for ages. haha...
ok, i'd better go before my head get more screwed up from the lack of sleep.
