just started getting migraines but i leave for vacation tomorrow

hello... what seems like almost out of nowhere i think ive began to have migraines. it started last week, when i suddenly lost all the feeling in my hands/numbness, and after, had an extreme pain in my head and severe nausea that lasted for 4+ hours. since this was the first time it happened i assumed i was coming off of the sickness i had. however, the same thing just happened again today.... sudden numbness in my hands/face, [this seems to be a called an aura or a warning sign?] and then a severe headache and nausea.

the problem is i leave for vacation tomorrow and i have no idea to prepare for a migraine if it happens while im out! i cant schedule anything with my doctor. wtf do i do? so far this shit knocks me out for hours, and i dont really have any pain killers, just advil, tylenol, aleve, and ondansetron. the ice cube method brings me relief, but i cant bring ice cubes around in my bag. ive heard of people drinking coke, but i just have orange crush and doctor pepper

please, if you have any tips for relief or what i should do when i feel it coming on... i would really appreciate it ☹️
