I ended up with a minor migraine this morning at work because I was inundated with stress after being asked to be on register for the first half hour of the store being opened and I had to deal with multiple difficult transactions in a row.
So yah...early morning stress, added on with some irritation at unexpected issues propping up triggered a migraine to start behind my right eye that hasn't gone away all day. XP Bleh. 
At least it's stayed as a minor headache. Usually about a 1-2 on the pain scale, but meds, shower, heat packs and eating food didn't help. 
So I'm hoping that sleeping tonight will have the rest of it go away.
We'll see.
