A dry hit, change to a new coil and while you are at it, change to a new juice flavor, something mint or menthol or a tangy fruit. I always tell new vapors to find a couple of juice flavors they like that are opposite such as if you like a creamy dessert flavor, make your 2nd juice a mint or menthol or a tangy refreshing fruit flavor and change between these flavors. I like dessert flavors but I keep another set-up ready with a refreshing fruit flavor and occasional puffs on that set-up keep me from getting the dreaded vapors tongue. It also helps to stay hydrated and drink lots of fluids.
