Please point me to FAQ or articles on Vaper's Tongue

Gosh I have seen links to blogs or info here on Vaper's Tongue, and now that I'm finally wondering about it, I can't find a thing! The last few days my juices have either had "little flavor" or kinda crummy (this is multiple PVs, and multiple tanks, some of which brand new, so it's not a "burned wick" etc). Not sure if I have vaper's tongue but want to read and find out--I wonder if just over-vaping could lead to this lack of tasting any difference? But that might be the same question...lol I do know i don't drink enuf water, I do a lot more now but i am not sure it's adequate. THANX

Thanks for help on this.
