Couldn't sleep

Ok so today I woke up at 330am with a huge headache...took some excedrin...didn't realize the caffeine would keep me awake...and couldn't fall back to sleep. I was tossing and turning and nothing. At 4ish I decided that if I am not alseep at 5am I will walk on the treadmill...beats laying in bed right. So at 5 I got my sneakers on and went on the treadmill for 45 minutes. It was actually a very good workout. Ended just in time to get ready for work. If this happened to me a year ago...the treadmill would not have entered my mind, instead the TV would have. Granted I did watch the news while on the treadmill but at least I got some exercise in on a day I usually don't do anything. YAY!!!
