One of my daughters has a perfume or body spray that I haved dubbed the "Headache Lotion." If she comes downstairs after using it, I get a crushing headache.
My first draw on a tank of alien Visions' Gorilla juice almost did the same thing. I think it's an aversion to esters, which have a strong banana-like aroma. Ales I've brewed at too warm of a temperature have come out smelling like banana beer, and have to sit in a secondary fermenter for weeks before the esters clear out and the stuff gets to be drinkable.
Fruity flavored liquids that contain any alcohol probably also contain esters, and those are known to make some people miserable (myself included).
