I'm using a Joye 510-T, and 18mg, PG, coffee flavored juice. I'm a pack-a-day analog smoker, that's why I went with the 18mg juice. My throat kinda hurts after half a day of using the PV. I can't sit down and vape for 3-5 minutes like I can with an analog, because my throat gets dry and I start to feel funny. This is really confusing, because everywhere I've read says the nicotine from PVs aren't as strong as they are for analogs, right? Does the type of juice have anything to do with it, like maybe I should switch to VG instead? Do other people who vape have these problems, and if so, what nicotine level do they chose? Unfortunately I think I'm going to have to go back to analogs for the next few days (because it doesn't hurt to smoke real cigarettes, how ironic is that?). I just ordered supplies to make my own juice, but the only stuff I currently have on hand is the 18mg PG stuff
