when i started using drippers and mechs, i was still using 24mg nic juices. its what i had at the time, so its what i used. i was doing dual coil builds at .3-.4 ohms. the first few hits with the high nic would almost burn your throat. then after a few hits i would actually get nic sick, start getting dizzy and tired and the sweats
its almost like at that point your getting double the nic when your sub-ohming and going for the bigger clouds
now i mostly drip 6mg and since my tanks are sub tanks i keep 6mg in them mostly too.... if i use one of my aero tanks or a non-sub RTA ill use 12-18mg
