I think it’s all about knowing your trigger and doing the best you can to alleviate the issue. For the last decade or so, since senior year of HS, I’ve gotten one roughly every 6-8 months, and I get them BAD. Unbelievable pounding, super sensitive to light, nauseous to the point of hurling a few times, etc. And this would last me for 4-6 hours. I remember vividly one during the night of the Marquette game in early 2021, when Polley went crazy in the second half.
I eventually found that they became slightly less excruciating if I took excedrin when I knew it was coming and just laid down preemptively in a dark room with a damp washcloth over my eyes/forehead.
However, after years of being petrified, knowing one was always around the corner, I now haven’t had one for well over a year (knocks on wood), because I realized that I always seemed to get them after intensely working out for weeks on end, and doing a very poor job of drinking water. Ergo, I postulated my trigger was dehydration, and since that inference, I’ve taken the obvious steps and have been OK.
That said, I still keep one bottle of Excedrin in my nightstand. Because you never know when it’s going to rear its head again.
Edit: also, the ABSOLUTE scariest feeling is when you realize it’s coming. For me, my vision can’t focus and I feel the pounding in the head start. Manageable, at first, but it grows exponentially. Usually, once I realize my eyes can’t focus, I know I’ve got 90 minutes tops before being immobile for a few hours. It’s a rush to make sure I eat something, chug as much water as I can, make sure all my work emails are replied to, etc.
