That's as may be but it still doesn't explain why vaping unlocks such extreme taste sensations in vapers. And it applies to nothing else that we eat or drink.
Not true, we do get used to certain tastes and start muting it. Personal example: I stopped drinking milk about 2 years ago, within a month of stopping drinking it, I found I couldn't handle the taste of it anymore, it tasted so off. So we definitely get used to certain tastes that we eat or drink every day, although not close to the extend that vaping does and there are probably a plethora of reasons for that, more concentrated taste, bigger coverage of taste buds, we vape a lot more than we eat (lol). Also remember that most foods we buy have a whole boat load of flavor enhancers, probably for this very reason, so that it always tastes consistent.
As for explaining why we perceive vape flavors so differently, your guess is as good as mine
This sounds like vapors tongue to me, I get it from time to time, quick solution:
2 shots whisky,
1 shot lemon juice
throw 1 shot whiskey and 1 shot lemon juice both in your mouth and swirl swirl swirl.
Spit it out when it burns too much, the second shot whiskey is to get the nasty taste outta your mouth afterwards.
