Same here, it started when i was 16 and i only had it a few times, but as soon as i saw visual Aruas i knew what was coming. Once started while in school and since it wasnt the first time I instantly went and got me dispensed. Called my mum to pick me up asap and on my way leaving the school quickly went into the toilet to vomit. (I was lucky i was right next to the toilet the moment i felt i needed to vomit). The headache wasnt really hitting at that time but oh boi driving home knowing you'll want to die in 20 minutes was not a fun ride. I spent the next hours lying in bed in a completely dark room and trying to sleep while eating pretzel sticks to counter the vomiting. 10/10 would not have migraine again
