So recently out of the blue I got a Vpro brand ejuice 0 nicotine that's 50/50 and I have serve anxiety. So yesterday I was vaping my bunk mate doesn't know so I hear her hustling about and panicked and then later my heart hurt to beat then ate and it hurt a bit more and then stopped but it scared me crapless I use to have anorexia so I can't tell if it's that side effect it use to happens when I didn't eat or if it's vaping ??
