I have a similar philosophy. Companies, if I see your ad for your dumb thing more than twice in an hour, I will never buy that thing. If I keep seeing the ad, I will not only not buy the thing but sneer at it in stores.
Another non-eater of fish – and all seafood – here. Had a run-in with fish once as a kid that involved the description “from both ends”. Taste (and smell) aversion has won all rounds since!
Hope you feel better soon!
