Sleepover Dilemma!?! Help!?

I'm having a sleepover with me and my friend Laura. I'm that kinda person who sorta has trouble falling asleep. So it's 4:20am, We were planning on staying up till 2 or 3. But she ended up falling asleep at 12:30am! So she is asleep now, and i'm awake! Everyone in my whole house is asleep! And i can't sleep! Me AND HER had 2 cans of Sprite, but it said 'No Caffeine added' So im not that tired! But she is...anyway i almost fell asleep, like i was comfortable, and 10 minutes passed and i was half-way asleep but not quite! So what do i do? BTW, i'm not even CLOSE to tired! And when i stay up 24 hours, during the day, i'm a monster! I am soooooooooooooooooooo TIRED! So any tips and suggestions? And im in my room so i can't go downstairs and get warm milk so any tips or suggestions of what i should do, and how to sleep faster? Btw, she is still sleeping!
