I fully agree - while I don't have a gag reflex, i do detest liqueurs ruining the flavor of chocolate, vanilla, or other flavors that are typical of deserts and that are the flavors i definitely do not want covered by something strong. But more than that I can't even stand to smell bitter almond or any almond extract (which is always bitter almond extract, since it tastes nothing like regular almonds) and amaretto.
I also am unusual in that I'm indifferent to wine for the most part. I do like beer (though i have a very low tolerance for alcohol, since one portion of it (a glass of beer, a glass of wine) makes me immediately feel floppy and this is definitely NOT fun, when you're with friends and you just want to fall asleep while the others are enjoying a meal or talking - a little less than that and i can feel silly and less inhibited, but it's easy to go beyond.
I can like some wines, and i can see that they do enhance food enjoyment, but I don't like the (perceived) sourness of them. I never "got it" about wine, and what a big deal it is, and how refined and amazing it is - yeah, i can get the complexity of flavor, i could probably be a wine taster, because i have a very sensitive nose (can tell what are the ingredients in perfumes for instance) but i just don't particularly enjoy it. I absolutely DETEST champagne. Makes me sick.
But the nausea reaction is different, i think. There are possibly three reasons.
1. I agree with chris.lawrence that from a physiological point of view allergy just doesn;t make sense physiologically. However I imagine it could be possible that someone might have a physiological reaction to a substance that causes a gag reflex in them and not in others. (Cilantro for me - never could enjoy mexican or indian food because of it. It's obviously a particular and individual way of tasting it - and there are no memories of it for me, since it just didn;t exist where i grew up in those days).
2. I think that he is also right when he says that smells are possible triggers for memories. (We don't have to remain in the 19th century world of Freud - modern studies on memory more than bear out some of these things that Freud originally said, before he rejected his trauma theory, to our great loss. But for sure the sense of smell is a very powerful force in evoking memory - it's closely tied to emotional memory. If you have any doubt of this, think how suddenly and unexpectedly smelling something you haven't smelled since you were a kid can bring you flying right back to childhood, whether positive or negative.)
3. We are predisposed physiologically to remember smells of things that once made us sick. This is obviously essential for a species that was originally a hunter/gatherer species in it's days of evolution. Those who didn't remember the smell of that poison mushroom that made them sick in a small quantity will end up dead one day for eating a large quantity! So we have predisposed nausea reactions to smells that we associate to nausea. It can even be a very accidental connection- like when you get a stomach flu just after having eaten chinese, or eaten watermelon, or eaten anything unusual or that tends to leave a long-term taste or repeat. You will feel nauseous when you smell it again even years later.
