Ended up with a migraine today towards the end of work.
Not even sure what caused it.
Maybe there was too much of a break between the Excedrins I was taking to stay relaxed enough to tolerate having to work another evening shift full of customer service.
Maybe it was irritation at customers.
Maybe it was irritation in general.
I know it spiked after having to deal with an indecisive customer who couldn't decide what fish they wanted and they had two children throwing a screaming temper tantrum and I just wanted to go clock out because I was off right then and hadn't yet finished closing and yah... *exhales* 
So somewhere in there the migraine was triggered.
I came home and tried to relax. Sleep. Take more meds. Take a shower.
But nothing seems to be helping so I'm pretty sure it's going nuclear....we'll see if I can get rid of it through sleep, but it doesn't seem likely.
