I have the occassional bout of insomnia, though less after cutting way back on caffiene and figuring out that B vitamins after 3pm were a no-no. I thought I was getting productive coding done late at night, but finally had to admit that much of my debugging time was going toward fixing those occasional late-night efforts. So when insomnia strikes now, I either pop a Melatonin, or catch up on surfing or light reading.

...

Later: Insomnia pays a visit, so it's off to the Monestary until the Melatonin kicks in.
