Insomnia!

How do you turn off your brain?  you lay down most nights and the next thing you know its time to get up.  But sometimes.....you remember weird things, like putting that box from your parents house in the garage, but you aren't sure where, or those 2 kids that drove you nuts back when you were teaching, or you get stuck trying to remember the last name of that poor child in your second grade that looked like she had BeriBeri.

  So you get up and take a valerian, and spend an hour focused on whether you can hear the old cat breathing, because it will suck if you wake up, move and you touch a dead cat in the morning.  Might be a panicky moment.  Then you get up, wash your face, make a cup of coffee and go read the news--which is a combination of horrible, ridiculous, and political, and takes about 15 minutes if you read the ads, also.

  Then you go take a shower, change the sheets (princess and the pea comes to mind), lay down and try it again despite the fact you need to get up in an hour or two.
