Reading this as I'm just coming down from a migraine. I've been getting them since I was a young teen. I get migraines with aura. They used to last for hours. Sometimes I get them multiple times per week, then they disappear for months/years and suddenly will get them again. No significant life or dietary changes in between. I've never been able to pin down what causes them.

These days they've become much more manageable. The aura and headache part takes 30-60 minutes as opposed to 5+ hours when I was a teen. I do experience brainfog, fatigue, dizzyness and nausea for 24+ hours afterwards, but at least I'm not stuck under the covers for hours.
