I just started mixing my own juice, and I bought my nicotine (36mg, 100%PG) juice from MyFreedomSmokes.com. I usually order my juices at 60/40 or 70/30 because I find PG to be irritating to my throat and nasal passages. Is is better to order my nicotine juice in 100%VG or 50/50 PG&VG and then add the additional VG to make it 70%VG and 30% PG? How does everyone else do it? I have calculators for juice mixing, but they don't show too many options for adjusting PG/VG.
