I had my first migraine during exam week of my freshman year in college in 1966. I had two days to study for one of my exams and couldn’t get myself to start cramming that early. I was stressing about not being motivated to study. The migraine lasted 24 hours, and I still had time to study for the exam. I had had headaches prior to this but nothing so severe. After that, my migraines took on a 24-hour duration.
