When my brain won't shut down for the night

I have a busy brain - it usually doesn't like to rest for a full 6-8 hours in a row.  No matter what time I go to bed, I'm typically wide awake starting somewhere around 2 or 3 AM.  These episodes of awakeness last anywhere from 2-3 hours, which is not fun.  I'm usually too lazy to get up and do anything, which makes the time pass slower, so I thought, why not use this time to blog and clear my head.  We'll see where this takes me as I go.
