I normally have a couple of headaches a week.
I've had them as far back as I can remember.
I'm pretty sure they aren't migraines because they typically aren't really severe.
3 advil usually takes care of it.
Occasionally I will have one that's really really bad and the Advil won't help. These are probably once a month, but still don't sound like migraines from what I've heard from people who do suffer from migraines.
EDIT: Costco has good prices on the twin packs of ibuprofen. Two bottles of 500 each for like $12.
