I don't mind 100% PG e-liquid but sometimes I want the vapor. Just wondering but do I lose any Nic level or flavoring if I add some VG (99.5% walmart brand USP) or add the same type of flavor that is 100% VG in an already Premixed 100% PG e-liquid? I don't want to rebuy a liquid just because I was unsatisfied on the PG/VG ratio.
