I just found out about vapors tongue. Makes sense to me, if someone vapes the same flavor over and over and over, so they simply cannot taste the flavor anymore. But that's not what I'm experiencing. My latest shipment of flavors, (the usual), one of the flavors not only didn't taste the same, but it has a strong chemical taste and if I vape more than a couple hits, I get a splitting headache! Now I don't know anything about vapors tongue, but if this is it, then it would be the first time in 3 years, and I have been vaping the exact same 6 flavors ever since!I I say it's got to be the mix. I think they must have done something different. All the other bottles in the same order taste exactly the same. They claim all is the same.I Iwill not yet say what flavor or by whom until they check it out for me, whichis what they say they'll do. Thoughts?
