Sleepwalking

I haven't had insomnia for years. I used to suffer from it all the time, my mind never shut down. It seemed like after some of life's biggest questions for myself were answered, it disappeared for the most part. I've been reading on other blogs I visit regularly that others have been suffering from it; I've felt serious empathy for them because I know what it's like. Wouldn't you know, it has reared it's ugly head again. I do get to sleep eventually, but I've averaged about 4 hours per night for the last week. So is there something in the universe affecting some of us or what!!??? I can't really say I'm under any unusual stress, I'm just lying there thinking in overdrive. There is a silver lining: I have been catching late night television that I haven't watched for years!
