Hello, I'm a long time smoker and used to vape about a year ago, started off with a eleaf istick 40w and a kanger subtank nano, started smoking again, and am now trying to ween off again with a new unit. Its a joytech cuboid and a arctic horizen subtank. Having a little trouble getting used to vaping again, I cant seem to do anything over 40 watts, even at a 3mg nic juice. I am thinking i may have a sensitivity to PG. As I cough a lot at say like 60 watts. Just wondering if there is such a thing as 100% VG, even if its watered down im ok with that.
