I have an NPRO, initially my wife and I both had one. I vaped almost an entire pack of carts (10) she did not like (menthol not strong enough (throat kick-wise)) in a day. These carts hold maybe 4 drops it seems. I then ordered some Dulcis 24mg from Vapor Talk, it is pretty tasty! I seem to be vaping 3ml/day dripping. I use to smoke 1-2 packs a day of Marlboro reds. Will dropping/cutting to 18mg still satisy the nicotine requirements in anyones opinion? In other words, is there THAT much difference between the 18mg stuff and 24mg stuff? Any input would be appreciated!
