Hot?

Warm, with a teaspoon of honey?

Milk, you see, has a natural sedative that comes into play when the milk is warmed up.
However, I often find that on nights when I can't sleep, it's because I'm
soo tired that I keep tossing and turning in bed because it's too comfortable when you're so tired. When I catch myself tossing and turning, I force myself to find one reasonably comfortable position and lie still as long as I can. It doesn't matter if my mind is racing, it doesn't matter if there's noise, just lie still, eyes closed. That usually does it.
If it still doesn't help, you could try to make a theta brainwave file with CoolEdit 96 (they have instructions on how to do so in the help file).
