Please help can't sleep and at friends house..?

I'm at my friends it's 2:15 am and everybodys asleep except me! I can't sleep cause I forgot my medicine. So I'm probablly gonna be up all night long and there's nothing to do my iPods about to die. So I'll just be layin here for hours and hours. And I really miss my family and my dogs and home. I really wanna go home but I can't call my mom it will only make it worse plus she's sleeping. So what can I do?
