I've been vaping 2 years and still can't quit cigarettes . I've tried different flavors, different PG/VG, tried MTL and got frustrated, played around with nic strengths...I'm currently vaping on a Wasp Nano RDTA. I've gone through a vape pen, to crap tanks and beginner RDAs, to the Pharaoh and now my Wasp. I prefer the Wasp best so far. I enjoy a 3.6 tiger coil at 30 to 40 watts. I'm getting vape mail tomorrow and my juice will be 6mg. I can add more nic if need be. But what nic strength should I bump it up to? I'm still willing to play around with different strengths. I currently vape 4.5mg and smoke 5 to 10 cigarettes a day. Is there anything else I could/should do to help quit?
