It's probably the late hour I went to bed, the restless sleep I had, and then the early hour at which I got up to go to work....but ended up with a slight headache behind my right eye today due to tense muscles in my neck. Thankfully taking some Excedrin helped it to fade away pretty quickly. Though it's threatening to come back because my neighbor is playing music so loud I can feel the bass from his music through the walls of my house like a second heartbeat in my chest and it's getting on my nerves.
