*Ice packs ASAP! I was using an Ace Bandage to wrap the varying sizes & shapes of ice packs to my skull & face but then I just invested in the Ice Hat and it has worked wonders. I highly recommend it, or one similar.
*Caffeine, I usually sip some coffee.
*WeatherX earplugs- these have really helped and it has a handy-dandy downloadable app that alerts you to barometric pressure changes in your area. You can also set the parameters if you know the high/low pressures that trigger you. And they are very affordable at $12 and reusable several times.
*Noise cancelling headphones, the soft padded kind
*If I get nausea, as weird as it sounds, I drink the heavy syrup out of a can of peaches. Basically the same thing as Emetrol. (Pediatrician told me that trick.)
*Then of course the usual abortive triptans that my brain just sarcastically scoffs at.
