Been vaping for 45 days but my "geographic tongue" has got so sore I've had to temporarily switch back to analogues (not happy). Tried everything to fix it, seen the doc etc etc, no joy. Been vaping 15/20mg unflavoured VG (occasional VG+2.5% menthol) mixed from Health Cabin products. So now my only option left is to try & find the least irritating / best quality / smoothest nic liquid and VG. And stuff the expense, whatever it takes, smoking analogues is not pleasant. If anyone can help out I'd really appreciate it. PS: I'm in Australia, vendors must be able to ship international.
