I am also new to vaping and tried Backwood Brews and it gave me a headache- I read the BWB is 100% VG, though it may be one of the flavors that didn't agree with me. Im trying to figure out if I need to eliminate VG or just BWB.
Backwoods is all 70/30 PG/VG, except for 2 flavors which are 30/70 PG/VG.
Not sure which flavor(s) caused your vaping-related headache, but I know I had a negative physical reaction to a clove flavor by Johnson Creek a while back. I used to vape plenty of juices from them at one point, and none ever caused me that reaction. So, for you it could be a particular flavoring, or it could be the PG.
Anyway, to answer the OP's question.. for me, the higher the PG content, the more I get thirsty & get the scratchy throat. That doesn't happen with a high-VG. (Also, a tank with a higher-PG mix tends to vape quicker, in my experience.)
Obviously the more VG, the thicker it's going to be, which can cause some performance issues. A lot can depend on what set-up you use and at what voltage/power/resistance.
To each his own, as we all have our preference. Your best bet is to experiment with the PG/VG until you find what best works for you.
