I'm new to vaping. Just got my starter kit in the mail the other day, but I'm waiting on a sampler pack of juices from Juicy Vapor.......Carmel Macchiato, Blueberry Coffee Cake, Juicy Fruit, Klua & Coffee, Peaches and Cream. While I wait, I'm using the Sweet tart juice I ordered with my kit. The vapor is harsh to me.....I cannot inhale it into my lungs without coughing. After reading a few threads, I think I'm going to buy some VG and dilute the PG/VG 14mg juice that's in the tank.
