Always a first

I've never had a hangover before. I've also never gotten drunk. I feel no urge to. That's just my thing. I like a margarita or two, and they may make me giggly and languid, but really, the most I've ever gotten is tipsy.

Now, I know a hangover is based on dehydration. Alcohol saps the body of water. Take, for instance, the stupidity of combining long hours in the sun, really hot days, and lots of alcohol. Seeing people be carried off on stretchers at an all day concert is proof that that combination should be avoided.

I personally have allergy issues. This means that, during allergy season, when my dog is shedding like crazy, or when I have a cold (hence a stuffed up nose), I inadvertantly sleep with my mouth open. It's a breathing thing. I like to breathe.

And I wake up dehydrated.

Heck, I don't drink enough water as it is. I know this. I'm actually constantly in some state of dehydration. *shrugs* So I guess my question is, considering I had a margarita last night, after a day of not much to eat, and it made me tipsy really fast, and I woke up this morning with a headache that's taken a while to kick the butt of, but also with bad allergy issues...

Is this considered a hangover or an allergy headache?
