I've had a headache behind my right eye for most of the day today. Pretty sure it's stress related since we've been prepping for the DM to come by to visit. And having the managers be stressed for various reasons is never good for my own stress levels. 
I've been surviving off of Excedrin and some Dr. Pepper though I do think the sugar content isn't helping at the moment, so I worked more to drink water instead as the headache seemed to spike after drinking the soda.
