I was correct in guessing I would wake up with the migraine I went to bed with. Because I woke up with it. 
Thankfully it wasn't a nuclear headache so while irritating, I was still rather functional.
And double thankfully taking some Advil, sipping at mountain dew and just working my muscles out doing the opening tasks at work helped to make it go away before we opened! Yay!! 
Though work did it's best to try and stress me out and get the headache back, I managed to avoid that (so far) so I can be more proactive today after work rather than doing nothing like I did yesterday.
