Mighta been vapers tongue. or you might have a future as a sommelier.
I mean... anything is possible. I will say (IMHO) nic (depending on the nic) can sometimes CHANGE a flavor more than it dilutes one. If you are all nic sensitive, you may want to look into some very pure nic.
Some flavor companies will add "extra flavor" if asked, that might give you a bit of wiggle room.
I am kind of assuming you are posting this outside of the USA where we are about to lose many of our premade juices horribly and indefinitely.
If that is not the case please visit the deeming thread.
