Ended up with a headache this morning.
I think it's mostly from tense muscles as my right shoulder up to that side of the neck is aching. 
But I'm not sure if it's just from sleep issues, or waking up at the wrong moment...
There was slight stress at work that made the headache slightly worse.
But getting some PastTense, Excedrin, a heatpack and a Dr. Pepper has helped it fade a bit. 

So we'll see.
