Ok, so I've been vaping off and on for about 3 days, and I really like it. I think I could actually lose the analogs, but I got this horrible cold. 8-o I'm not sure if it's from the PG i've been vaping or if it's just a cold, but i've decided not to use my PV anymore until i get over the cold. I've read somewhere that PG can cause problems and some poeple find relief with VG....but which suppliers are best to buy VG from?
