Anything over 10mg on a sub ohm has my eyes wide open, like I’ve had 10 cups of coffee. I’ve no idea how you cope with 18mg. But as you say, maybe it works if you only puff on it every now and then. Interesting.
no idea what sub ohm means but i vape 12mg nicotine liquid, i started at 18 but find 12 works fine. I use a cheap Apire model and they usually last me around 3 or 4 months before i need a new battery.
