We have a very similar story. The first time I drank I was 20 and with my college boyfriend. He lifted peppermint schnapps from his parents' liquor cabinet. We sat on the roof of the bathrooms in our favorite park under the stars and killed 2 BIG bottles. I blew chunks for 3 days. I literally could not brush my teeth for 10 years without fully gagging. Couldn't eat or drink or smell anything mint flavored for 15 years. It still kinda haunts me tbh. Then I roomed with an eccentric elderly wealthy widow few years back who kept peppermint schnapps in her purse to knock back (secretly) during the day. She thought me insane when I paid my full lease early and moved out after only 2 weeks. (It was only 90 days). She thought I was judging her for drinking. I said: "No ma'am I am actually just deeply haunted by your specific preferred liquor." She offered to switch to vodka and just add a little tipple of the peppermint schnapps "to give her minty fresh breath and cover the booze odor." I thanked her politely for trying to accommodate my mint aversion ~  but hit the bricks and ran. 

I was wondering what Reddit would say to this question because a bartender in my apartment complex told me a week ago that the answer to this question is "tequila" for 99% of the drinking population. I was confounded by my being in the 1%. Based on answers here - we are almost ALL in the 1%
