My girlfriend and I are interested in trying some more 0 nic juices but I'm having some difficulty finding them. Also, I've noticed that I'm getting a very dry throat and my lungs seem to swell up when I'm vaping. I'm using Johnson creek original juices (not a huge fan so far) and I'm wondering if this is because they are PG juices but I'm not sure. Any suggestions on some good VG vendors? THANKS!
