How do you know whether you have migraines vs. headaches?Because I seem to get headaches triggered by too much sodium, too much caffeine, too much sugar, when I'm tired, when I'm hungry, when I'm stressed, when I'm dehydrated etc. I'd always assumed that they were just headaches because at least half the time I could figure out one of the above that might be causing it.But at the same time they often seem to fit the symptoms list for migraines with the nausea and sensitivity to light/smells etc.
