Aids other than emergency meds?

I’m sitting at my desk at work and an aura just popped up. It’s slowly expanding, doing its thing. I actually can’t see the left half of my keyboard/screen rn so please excuse any typos.

What do you guys do when you feel a migraine coming on and you’re not necessarily in the most ideal situation? I don’t have emergency meds so wondering what else I can do the moment I feel something (like now).
