Hi guys, I've been vaping for about 5 months but have recently started getting consistent heartburn (or what feels like heartburn). Been vaping the same juice (Menthol from healthcabin) so it's nothing to do with that. I have however just switched to a Vivi Nova tank in combination with my Ego Twist. Has anyone else had this experience? I've read other posts that have said that it happens when you swallow the juice, but that's just not the case here. Any input would be fantastic. Cheers!
