I realise this is a bit late, but here's some advice for the future. Aside from stealing your parents alcohol and falling asleep easily to a nice buzz, you may want to try meditating before you go bed. I recommend an Android/Apple app called 'Headspace'. It's a series of guided meditations. After you finish one of the sessions, you won't feel excited or nervous or anything. Then, as you go to sleep, keep concentrating on your breathing like the meditation app shows you. Just focus on your breath and if you get distracted by any thoughts, return to focusing on your breath.

As others have also suggested, a soft constant noise (like the whirring of a fan) will help you get to sleep as well. On top of that, being cool from the fan puts your body at a temperature more conducive to falling asleep, I've found.

Happy dreaming!
