Seriously though, I will pee if I can. If that doesn't work, I'll go downstairs and sleep on the cold leather couch. At school, I'll usually just sit there and wait for it to happen since I'll have class in the morning. Or I give up and I watch TV, a movie or video games. For the most part, I don't go to bed until I'm tired and actually need to sleep.
Masturbating helps sometimes too. 😉
