Migraines and caffeine are not correlated, with rare exception like a food allergy to caffeine, coffee, or milk. However, tension headaches and caffeine are strongly correlated. I don't drink much in the way of caffeine. When I drink coffee I drink decaf. I also drink decaf tea sometimes. I also drink irregularly. I'll go a week or two without any decaf or anything and then another week drinking six cups a day.
