OK it's nearly 2 in the morning here in England and I can't sleep, everyone in my house is fast asleep, my GF fast asleep, I have no one to annoy. I'm wide awake like its midday or something. I also have a strange urge to do uni work, even though I have almost none to do atm.

I'm usually asleep by 11 and up by 7 so this is really wierd for me.

Does anybody know any tricks to make myself fall asleep?

take a sleeping pill

Listening to some minimalist ambient usually helps me. Try Steve Roach's "The Magnificent Void" or Bass Communion's "Ghosts On Magnetic Tape." Turn the volume low and concentrate on the sounds.

Failing that, are you old enough to drink? A couple shots of whiskey and I'm often out like a light.

Down a .5 liter of vodka knock you right out.

take 2 nyquil wait 15 minutes....and your done

 Yup, i'm old enough, I may try a shot of whiskey then

@ sherlock - I would but I don't have any 

The last years I fall in sleep with just drinking something like beer/vodka/whiskey etc..

Or it makes me atleast sleepy :).

I have problems sleeping all the time, but i have found that watching a movie helps me fall asleep.

light instrumental music

i usually watch some tv
