Hmmm when I smoked analogs i was 2.5-3 pad full flavor cigs. Now i'm on 30 mg nic and I'm vaping about 2.5 ml a day chain vaping. But remember that they say that we get just 1/10th of the nic from vaping that we used to get from regular smoking of analogs. You will taper down once your body gets used to the change from vaping. So don't worry just enjoy your new lifestyle and drink a alot of water.
