I am the kind of person who color-codes her grocery list.
So when migraines started taking over my life three years ago, I did what any obsessive person with a chemistry degree would do. I built a spreadsheet.
Date. Time of onset. Severity 1-10. Suspected triggers. Foods eaten in the 24 hours prior. Hours of sleep. Menstrual cycle day. Weather. Screen hours. Caffeine. Hydration in ounces. Stress level. Medications taken. Recovery time.
For three years I logged every single attack. 1,247 days of data. My neurologist thought I was overdoing it. My husband stopped asking what I was typing.
I kept doing it because somewhere in that mountain of numbers there had to be an answer. There had to be a pattern. Migraines do not just happen. They have causes. I am a science teacher. I believe in causes.
Then one Sunday afternoon in October I made a pivot table that changed everything.
