So if you have migraines, it is not normal. It is not incurable either. Use pain killers when you must, but keep looking for a solution.
The solution can be different for everybody. Start with diet, it's a very common cause for it. Don't limit yourself to what you think is right. Try things, even weird ones. Took me 3 decades of trials and errors to not need pain killers.
OTC pain killers (and even prescribed pain killers) don't really do anything for the 3 people I know that get migraines. These people have to lay down under their sheets to block all sun light, they can not do absolutely anything at all during the episode but block sunlight and hope whatever medicine sort of worked last time will work this time.
Preaching and generalizing from your mild case helps no one.
Unfortunately, I don't think people understand how long it takes to get a grasp on everything we ingest. Someone in a sibling comment mentioned giving up after just a few months of "logging" their diet.
It took me years to narrow down an allergy/sensitivity to tannins. And it also took years to recognize the full extent of sugars' effect on my body.
