12mg is where I started and where I'm still at. I've considered dropping to 6mg but afraid I'll go through juice twice as fast to compensate. I pretty much chain vape as it is so 6mg might never happen. The flavor is more pronounced with 6mg for sure though, I've tried friends' juice at 6mg and I'm jealous! the flavor doesn't "pop" as much with 12mg. Boo!
