Ik heb zelf nog nooit een vaperstong gehad. Lees je wel dikwijls van mensen op forums...meestal dampen die wel al lang. Weet niet zeker of het dat is wat gij hebt. Ik weet ook niet of al die middeltjes helpen, zijn ook mensen die zeggen dat dit kwatch is omdat je het meeste smaakt met uw neus.
Google vapers tongue maar eens
First world problems, vapor's tongue : electronic_cigarette
This is the biggest source of mis information and misunderstanding in the vape community. YOU TONGUE HAS NOTHING TO DO WITH IT!! Stop calling it vaper's tongue.
Your tongue tastes 5 things: sweet, sour, salty, bitter, and umami. That's it. Your tongue DOES NOT taste pizza, strawberries, cola, whatever. This is the job of your olfactory sensors at the top of your nasal passage. Chemical signatures combined with sense memory makes you think strawberry, for example, when you smell something similar but not strawberry. You are actively recalling a mental image of a strawberry when you smell these scents. You learned the association. That's why a real strawberry and that artificial strawberry gives you the same response even though the two really don't smell the same, but you still think "strawberry". In contrast, salt is salt and you don't have to recall salt to know salt.(it's actually a very specific chemical that your taste bud senses, sodium chloride).
Now, as for why you cease tasting your juice favors after a while, its called olfactory fatigue. When our olfactory senses get bombarded by a particular smell, it eventually gets ignored. An analogy would be the dairy farmer. If you ask one if they are bothered by the smell of cow manure, most will say they don't even notice it anymore, but if you or I were there, we would smell it immediately.
So, how do you solve this problem? Easy. There is a technique that chocolatiers, perfumers, tea buyers, spice merchants, anyone who professionally uses their sense of taste and smell (which essentially the same thing) have used for hundreds of years. They shock their olfactory sensors into "resetting". All you have to do is open a bag or can of freshly ground coffee and take several deep inhales. Be careful not to actually inhale any grounds. The unique molecular structure of the coffee odorants does this "resetting".
No amount of brushing your teeth, gargling, or any other anecdotal mouth oriented techniques work well or at all. It all comes down to simple high school chemistry and biology.
TL;DR: your tongue has nothing to do with it, it's your nose. Fix it by deeply smelling fresh coffee grounds. Don't inhale coffee grounds.
