Need to wake yp early!!!?

Im a science student with no time. I have classes at 8am, stretching till 8pm and i come home around 10. Then I have to go out to eat, print notes, get stuff, and come home. After that I need to study, do lab reports and such. And I cant seem to wake up for my 8am classes which is everyday and I miss them. WHAT SHOULD I DO????
