Oh, I know, when I've tried to drink so much water for the vaper's tongue, sometimes it seems to help. I can take a new juice and taste it and then before too long I barely taste it. Tooth brushing does help. Maybe I should fill a tank with butterscotch and see if it's OK. I tried that after vaping cinnamon roll and it tasted disgusting! Same results if I filled the tank with any other of the ones which blend OK among themselves. So butterscotch needs a clean tank and coil. I do want to see if it's vapable. And if I keep them after a bad first try, they can taste fine at some later time.
