Have you considered improving your atomizer?? vaping that high a nic, you have to be vaping at pretty low power (high ohm). Better atomization means you can use less Nicotine per ML to get your current dosage.... This is the BIG reason why you see/hear those that go sub OHM often reduce nic content.. They are using MORE juice per puff, therefore atomizing more nic per puff. In order to maintain dosage they reduce concentration. Not say you need to go SubOHM, might just need a better atomizer.
Does anyone know of a "better atomizer" that's compatible with the Nautilus (not a mini) tank? I love the 5ml capacity (I only have to refill it about every 3-4 days; again, lazy - maybe I should consider a screen name change request...)
