Great tips Abe_Katz! And well organized to boot! 

I usually introduce liberal amounts of hot sauce into my life and that seems to keep vapor's tongue at bay. Course, hot sauce is usually my cure for most everything.
Reminds me of the song...I like all the great tips here and will offer one more. If you are having a particularly bad episode get yourself a jar of unrefined coconut oil. The refined works okay too but the unrefined has a more pleasant flavor. Take a tablespoon of the solid coconut oil and let it melt in your mouth on your tongue. Try to hold this in for about 2 minutes after it fully melts then spit it out. Do this a couple of times a day for a couple of days and I think you will find it really speeds up the efficacy of the other methods mentioned here. And the person who recommended coconut water is spot on. It is a fantastic hydration drink and tasty to boot without a bunch of artificial crap and sweeteners.
I just bought a kanger t3 and it did helped with my vapers tongue!!! not completly out but beginning to see the light again!
I've not heard of a Kanger T3 doing anything for vaper's tongue. Though I will say that in my opinion that T3's are a pretty good clearomizer and that in my experience they handle higher VG juices better than other clearomizers. (Please note I've not tried every clearomizer out there--my experience is limited, I'm still a pretty new to vaping.)
I did notice though that as I've slowly been over coming my vaper's tongue (I had a rough patch where I couldn't taste anything at all). that I did notice that on some juices using standard resistance heads gave me more flavor while other times using low resistance heads did.
So I think iam going through this now or on the brink of it as juices that tasted stronger yesterday and the last few weeks don't seem near as tasty today.. I kept thinking maybe I was not grabbing the right bottle etc...
I don't drink water but I go through a ton of tea a day which is as we know mostly water....will that suffice for hydration? As I assume the water is for hydration.
