I got into vaping *hoping* I could drop nic but not about to stress myself out about doing so. Started at 12, couldn't put the PV down. Went up to 18, still chain vaped a lot but could put it down and walk away whenever I needed to (including going to the store etc without needing to bring it with me). After about 6 months, I dropped back down to 12 comfortably. Then I got a rebuildable dripper and dropped to 6 within a week. I still vape the same way - chain vape for 20-30 minutes, then set it down for a while - so over time, and with more efficient equipment, I have successfully dropped my nic. I still keep 18 and 12 around for emergencies, and for when I'm in situations where chain vaping isn't an option.
