Just a couple of quick add-on questions. Great community here! So I've noticed that being a long time pack a day smoker (30 odd years), and using direct to lung and not mouth to lung hits off both vapes can give me (sometimes) coughing fits. I'm vaping mostly 12% nicotine juice. I've heard some longtime smokers get this when switching to vape. Is this something that will go away over time? Is there a specific airflow on the tank that might help in the transition? Does the 12% nicotine ADD harshness over say a 6% nicotine blend?
Pack a day for 30years, on a MTL I'd suggest a 12mg to 18mg, starting at the 12mg first if the nic cravings are down right attrocious I'd suggest bump up to an 18mg afterward. Now moving to a sub-ohm device which can vaporize 2X on up to 8X the juice thus 2x to 8x the nic exposure per hit, I'd suggest a 6mg if you were in the 12 to 18mg MTL ballpark, if at a 9mg or lower on a MTL then a 3mg for sub-ohm and especially for a super-powered sub-ohm, which around 80watts you'd probably need a 3mg to 6mg range. A lot of variables to take into consideration, but those are the ballpark starter levels I look at when giving advice on nic strength needed.
