I'm finding it particularly hard to google this, but want to know if there's a word or expression used that describes the scenario when a person stops liking a food or drink after they have vomited after eating that particular food.
Sorry for the slightly off-putting question!

It has a rather generic label--a food or taste aversion--often trauma-induced, as you described (but just as often not)
Merriam-Webster online
Here’s how taste aversion works: You and your buddies go out for a few drinks. You’re young and wild and love drinks with the strong coconut flavor of Malibu Rum. Things get a little out of hand, and you spend part of the night praying to the porcelain god. You recover, and next weekend go out for drinks again. The bartender passes you your favorite drink, but this time the smell of coconut immediately makes you want to vomit. You loved Malibu for years, but now, the very thought of it makes you sick. What you’re experiencing is your brain protecting you from being poisoned. When we were primitive creatures, we weren’t sure what was safe to eat so we tested things out.
If you survived the experience, your brain had to make sure that you never ever ate that same thing again. So, if you ate something that made you feel ill, your brain decided "better safe than sorry," and conditioned you to feel sick anytime you saw, smelled or even thought about that same food.
