I'm apparently allergic to PG, probably flavorings that are made with PG, and maybe some flavorings. Bummer, huh? Well, I've been trying to mix some that I hope will work for me but not sure what I'm doing, other than a little info and a mixing calculator gathered so far. So if anyone can answer: 1) How much distilled water should be mixed w/VG so it's a good consistency (not too thick) for cartomizer health? 2) What percentage of VG (w/water included) to a percentage of total flavorings works best? In other words, I'm guessing about 75% VG w/ water to 25% flavorings. Yes? No? Maybe? Thanks.l
