Permanent link for Steve Pavlina on how to fall asleep quickly.

Here's a method I've found for dealing with my occasional insomnia-- I can slow down my heartbeat. I become aware of my heartbeat (pay attention to inner chest area-- trying it now while I'm sitting at the computer, I found it helped to start by using my fingers to feel my pulse at my throat), observe the rhythm, then imagine a slightly slower rhythm, which my heart then follows.

I realize this involves some sub-skills. I don't know how common they are, or how hard they are to acquire for people who don't have them.
