How Do I Keep from Falling Asleep During Homework?

OK, so I started doing my homework around 5:30. Its 7:20 now i'm almost done but I can barley keep my eyes open. I have to read a chapter from a novel we're reading in class and do a little more math. I can do the math, just not the reading. I have to read this because we are having a test on it tomorrow. So can someone give me tips to stay awake? (I'm not allowed to drink coffee. I'm not taking a cold shower either)

Suggestion:

first of all….. Go look up the book online . After that go to sleep if I were you i'd start going to bed earlier
