vape tongue is actually misinformation. It's more about sensory overload and recovery. Smoking all these years have dulled and destroyed our taste buds. After quitting they are now on the slow process of recovery and repair. One starts tasting again and
vaping, and discovers taste we've long lost the ability to taste. Now the poor little recovering taste buds are being subjected to intense new and old taste and get overloaded and stunned. It is not do to the
vape in particular, it's due to everything you are tasting, the coffee, the tea, spicy foods, and vape. All these flavors that were denied full sensory input are now being subjected to your newly recovering taste buds and oral factory senses. Then only thing that really helps them is time to recover. It's like any other muscle or organ that gets over used and abused, give it a rest and all will be better in time.
