Insomnia and the unmotivated

I'm going through another bout of insomnia.  No, there is nothing burning in my mind, my subconscious is not yearning to overflow me with grand insights, I simply woke up at four in the morning and could not go back to sleep.  So, what does the unsleeping Mom do?  she plays around on the internet waiting for the rest of the house to wake up.  I think I need more interesting hobbies.
