I have the same sort of problem. On one side of my house, there's a family with a teenage son who constantly throws parties (They get so bad, after one party, we found puke in our garden, not to mention a tonne of rubbish) and a few doors down on the other side, there's another family with a teenager who as of late has been throwing alot of parties. My best advice? Close all your windows, pull down all your blinds, turn off anything causing noise in your bedroom, go back to bed, pull the pillow up over your ears, and if you can still hear it, I know this sounds cliched but I've found that if I can clearly hear the music they're playing, try and get into the groove and the lyrics of it, and soon you'll be fast asleep (Trust me, a few weeks ago they were playing day n nite so loud, I could clearly hear every note and word, I tried going along with the song in my mind, next thing you know I'm fast asleep).
