I was right in that the migraine would last into the early hours of the morning.

Thankfully it had mostly faded by the time I officially woke up, though I ended up taking an Excedrin not long after waking up when the muscles in my shoulder started to tense up again. 

Mostly I've been keeping it pretty mellow today. Keeping a heatpack on my shoulder and drinking some Dr. Pepper consistently throughout the day since the caffeine seems to be helping currently.
