It kind of started around late afternoon yesterday, no aura this time, and lasted maybe 24 hours? It faded off around 2-ish this afternoon. I took some painkillers last night and managed to sleep through some of it, but I kept waking up every couple of hours and trying to shove my head through the pillow (putting outside pressure on that side of my head either helps or temporarily distracts me, I'm not sure). And then I went downstairs this morning and my dad decided to test a new lightbulb and basically stabbed me in the eye, so I took more painkillers and went back to bed until it started to fade off.
Consequently, I'm now tired and maybe a little cranky. But hey, at least this one waited until a day I wasn't supposed to be working. I won't have to make up any more time because of it.
But, yeah. Apparently more stressed than I thought? (I probably ought to have a better measure of when I'm stressed than waiting until my body does something funny, but I'm bad at judging emotions without outside proxies -_-;)
