Another one of those theories I have, but not one I’ve bothered to Google yet, because, um, my head hurts too fucking much to do it:

I’ve been a smoker for the majority of my adulthood, except for my pregnancies (for those, I’d quit until after delivery, and within a few months after, would go back to smoking again).

But I’ve never suffered from migraines except for during the time that I quit smoking (because it was bad for me instead of because it was bad for a child I was carrying). When I started smoking again shortly before my ex-husband and I separated, my migraines also faded away.

I never considered any correlation between these two things until now – because I’ve quit smoking again, and wouldn’t you know it, the damn migraines are back (and with a vengeance).

Bah. Time to go bang my head against a wall (yes, it actually helps to do that when the pain is this bad).
