Flappers posted... What you're thinking of is called an olfactory hallucination -- it's smelling something that isn't there. It occurs when a person isn't smelling or tasting any food or drink. It just happens randomly.
It certainly isn't what I experienced. I just didn't like the taste of apple cider...
If I went to a doctor saying what you did I'd sound like a hypochondriac.
If you're serious that it literally smelled and tasted like vomit, that's not normal. I'm not saying to go to a doctor and tell them you think you have a brain tumor because apple cider tastes bad. I'm saying to make an appointment with the specialist that treats smell and taste disorders, tell them what you experienced, and let the medical professional take it from there. Smell/taste disorders are a lot more common than you think and there's nothing weird about consulting a doctor about this, particularly if you continue to have similar experiences.
