Good morning everyone. I've been vaping for a few days and noticed that when I breath in there is just a little chest pressure. I was thinking it might just be heartburn though and that surely could be it. I don't think I drink enough water either. Could someone chime in if they had this pressure problem when they started vaping? It's not like bad pain, don't want to worry anyone. I've been really burping a lot and i never do that...I'm vaping straight pg @ 18 mg Thanks
