Chamomile Tea at 2AM

I woke up at around 1:15 this morning after almost four hours of sleep. I had a nightmare about a dog attacking me that I just really couldn't shake. Then of course my mind started to race with all sorts of thoughts- about work, about the wedding... about everything. Why is it that when all you want to do is sleep your mind doesn't cooperate? After 45minutes of laying there completely awake I decided to get up and make some chamomile tea. I really hope that this will make me drowsy again.... I want to get back to sleep. There's only so much mundane websurfing you can do at 2:30 AM! Maybe I should count sheep...
