Sex and the City... and a Run

  Once again, I learned a lesson about my running this weekend.  I had planned to go for a morning run on Sat. but instead I slept... and slept and slept. I guess I was more exhausted than I originally thought.  I believe I napped more than half of the day today.  It's kinda sad but honestly felt good.
  Around 2pm I decided to get off my ass and go for a run.  Prior to that I'd gone back to my apt to take a shower... but it was super cold so I ended up cuddling on my couch and falling asleep. :(
  I figured there was a nice enough breeze so it would combat the 90 degree weather.  Wrong.  The breeze helped to keep me cool but the sun killed me.  I got dehydrated really fast and ended up running a little over 1 mile before dying.  I walked a little over a mile as well so in the end I did just over 2 miles in 30 minutes.
  I am going to try again tomorrow but probably at the gym instead.  Tomorrow's goal is to get at least 2 miles in so I'll have around 10 miles by the end of the week.  When I got back to the car I stretched and then downed 30 oz of water before I even left the parking lot.
  Today I also took a rest.  I figure I deserved it.  I spent a while cleaning the bathroom to break up the naps and episodes of Sex and the City.  I am not one of those people who can just relax and even though I haven't walked more than 2 miles today, I have kinda enjoyed it.  My only fear is that when it comes to bed... I will be so relaxed that I won't be able to sleep.  Which is almost every Sunday night.
  What types of things help you fall asleep?  I've tried tea and it doesn't work for me but I am open to almost any other suggestion!  Give me your best advice, please!
