I Can't Sleep

It is almost 1 in the morning and I can't sleep. There is a snoring shih tzu at the foot of my bed and I am the only one awake in the house. I've had milk and cookies, read in my book, late night texted my boyfriend (who's asleep), and have watched several episodes of The Addams Family on hulu. All of these things normally work and none have seemed to tonight. I think I had to much caffeine today. Hopefully I'll fall asleep soon. I hate not being able to sleep.
