--- Quote from: Papersatan on 13 Oct 2012, 16:07 ---Some people get an aversion to certain kinds. I won't drink southern comfort. the only two times I drank it I threw up later that night.
I think the hangover might be too far removed from the drinking to trigger it. I threw up while still drunk and could taste the Soco which made the two connected for me.

You'd be surprised how far removed the nausea can be from the initial food intake. I think it can be as long as 24 hours, if not more. It's an extremely robust evolutionary adaptation; the negative association can last as long as decades without being reinforced beyond the first time.
Why it doesn't happen with alcohol is puzzling. There's probably a habituation element involved, where your brain learns that it's okay to be nauseous after drinking alcohol, since you do it so often, so it must be for a good reason. Except, the nausea reflex also happens when you've gotten sick from eating something that you eat every day, so the association still happens if you're used to the food. Yeah, I don't understand either.
Is it cold in here?:
Also, the body should recognize ethanol as a poison if it's consumed at high doses.

Oh wait, I think I got it. You see, the body can only defend against organisms and foreign organic molecules that are harmful to it, but it has no immune response to simple chemicals. Food poisoning is almost always bacterial or viral in nature, which means the body can mount an immune response to it. The immune system signals the brain via the gut nervous system that something is wrong, and the brain recalls what it tasted or smelled most recently, and tells you "Don't eat that." Regardless of whether it's usually poisonous or not; the brain nor the body makes that distinction.
This doesn't work for alcohol, because there's no immune response to it. Instead, alcohol goes directly from the stomach into the blood, and to the brain, where it starts wrecking shit, and then the brain induces nausea because it, and not the body, is sick. Which is why it doesn't create a lasting negative association: it's not using the proper pathways. Sneaky bastard, that alcohol.

Well damn, when I search my name I get myself, my grandfather and my great grandfather. :-\ Didn't think that my name was that unique... in fact, one of the results was the White Pages, where it shows that I'm the only living person with my first and last name... I'm also apparently the only person with my username on the internet.
...
Suddenly I feel so very unique and the warm fuzzy feeling of being this individual is slowly fading into an odd sense of fear at being the only one with my name and people finding me strange because of it...

I'm apparently a famous hairdresser and the CEO of Lloyds. Why was I not informed and where are my bonuses?
