How can I stay awake the whole day?

Like a couple days ago me and my friend had a sleepover, anyways we ended up pulling an all-nighter. At about 1 at noon or so, I was just gonna take a 2 hour nap.. But it ended up being a 7 hour sleep!!! WTF? So, I woke up at nine, then I was up all night .. Then I managed to fall asleep at 5am and then I awoke at 10. That night ( last night ) I fell asleep at 8pm, then I woke up at 2am because I wasn't tired. But now, for me, it is 7:15 , and I am exhausted. I can't fall asleep because I have plans for this morning and all day. How can I stay awake without caffein until like 10 at night ? Please help !
