Same here... started on 18 (and a few 24's)... About 8-months later, my favorite juice was only available in 12mg, so I tried it and didn't die, go into a withdrawal-coma, or even notice... After that, I decided to try things in 3mg (and even cut them lower for RDA use), and happily vape 3-6mg daily now. I can also go nearly a full day without touching a vape, but I think I crave the flavor more than the Nicotine!! However, on a stressful day at work (or home), a few hits of 18mg do take the edge off
