Insomnia

I've had only a few good nights sleep in the last few weeks, one of which involved a sleeping pill. I have no problem falling asleep, but I wake up after a couple of hours and then toss and turn for the rest of the night. For those of you not intimately familiar with insomnia, it leads to a certain fraying around the edges, an exhausted, pale view of the world. Suffice it to say, this sucks.
