I find VG less dehydrating and fuller/denser/moister in vape quality.
It's funny you should mention that. Since I started seriously vaping I *always* keep something nearby to sip on. I've noticed that higher VG doesn't dehydrate me as much as higher PG concentrations but... I'm also a mustache kind of guy! Today I noticed, when I blow out a BIG cloud of vapor, my mustache has tiny mist droplets in it, like walking in a dense fog. I don't remember the high PG juices that I started with having that effect
