I have been vaping - and cig free - for a little over a month. For the last couple of days, I can't taste any flavor of my e-juice. It's just nothing no matter what I vape. I heard something about "vaper's tongue" which seems to describe my situation. But what I don't understand is when I first started vaping, I could taste the flavor no problem. If it s a case of vaper's tongue, wouldn't I experience that from day one but not a month later?
