My nic level dropped with my gear upgrades too. 2+PAD for 26 years. Started at 24 and had the DT's even at that level till I got a nautilus. Over a couple of months I dropped to 20, then 16. When I moved up to RBA's I dropped to 12. My first puff off of an rda at 12 was one helluva rush! Lol! So I dropped to 3 and got used to it, even in my Kayfuns. I'm mixing my own at 3.6 now and it works for me. Still get a lil rush if I chain-drip, but I kinda like it once in a while tbh.
I used to have other bad habits too, so a lil rush now & then helps keep me on the straight & narrow in that respect as well. vaping saved my life in more ways than one.
