This week at work has kicked my butt. I have been drop dead tired every morning when I've woken up and every night when I get home I've wanted to collapse into my bed. Last night I fell asleep around 9 p.m. And it's only Wednesday.

But last night I also managed to get in a speedy (by my standards) six miler. I'm not sure where I found the energy. I literally dragged myself out the office collapsed in my car and thought I was going to fall asleep on my two minute drive home.

But the crisp fall air must have invigorated me because I got home threw on a long sleeve tech top and some shorts grabbed my iPod and was out the door. I clocked the six miles in 1:02.10. I felt great the entire time. My left knee hurt for a second in mile five, but went after that.

When I got back home though, my right knee was acting up a little bit. Nothing too serious, but it caught my attention.

I slept a lot better last night and I have to credit that to taking the melatonin. I had stopped for a while because I wasn't having any problems and I don't like taking stuff if I don't need to. But man it makes all the difference in the quality of sleep I get. I'm 99 percent sure I'll be taking it again tonight. (I mentioned the melatonin in a post a while ago, but just a reminder, it's not a sleeping pill, it's a supplement my doc. recommended that helps your body sync to circadian rhythm.)

Anyway, after an awesome night sleep, I woke up this morning to meet Michele at the gym for spin class at 5:45. Except Michele wasn't there when I got there. Turns out she had way overslept. No biggie though. I didn't stay for the whole class because I had to bounce out to get home to shower and get ready for work, but I did about 45 minutes and felt pretty good. My legs weren't too tired from last night's run.

However, when I got home my right knee was acting up. It buckled three times when I was walking around the house getting ready for work. Not cool.

I'm skipping my soccer game again this week because I don't want to aggravate the knee. Instead I'm going to ice it down and watch my Phils in the World Series.
