So.. I think I'm allergic to VG. I can take it at very low levels but the coughing sucks enough to try the 100% PG. What will I be missing out on without the VG? Anyone have advice about where to order juice with high PG levels that isn't expensive after cost of product and shipping? I dig the Dekang they have the higher PG but the cost after shipping is enormous. Boy I can't wait to find the perfect system for me, I know it's out there.
