Quick intro. Started vaping with V4L early this year, quit and went back to analogs after a few months because I thought I was allergic to the PG and it seemed the 100% VG wasn't giving me the same satisfaction. I decided to give it another go this past weekend, ordered some new VG cartos with higher nic and figured I'd use the carts I had left (some regular and some lower-nic 100% VG) while I waited. Well, no allergic reaction problems until today. Over the weekend, I vaped some Ry4 and 555 regular, some VG vanilla and 555, and no problems. This morning, I popped in a regular peppermint ice cream (one of my favs) and the symptoms started right away. Could it just be the flavor I'm having an issue with and not the PG? Anyone heard of this and if so, any clues as to what ingredients might be causing it? I'd love to get off analogs 100% again, but the allergic reaction is tougher to deal with than going cold turkey, and I need to avoid what might be causing my discomfort. If I knew what kind of flavor profile to stay away from, that would be a big help. Or could this just be that the PG levels finally built up enough this morning to make a difference? Gonna stop with the peppermint IC right now and see how it goes. Just curious if anyone else has experienced this or heard of something like it.
