Been vaping for over 2 years and have eased my way down from 24 mg to 6mg. I've been using 6 for over a year and have tried 0 in bursts trying to erase the nic altogether, but I always find myself the next day grabbing the 12 for a chain vape session. Just can't stop the cycle. What have others who have totally dropped the nic done to get over that hump?
