For me dry mouth is caused by nicotine. I can vape 100% VG and get a dry mouth if i've made it with too much nicotine for me and like others say it doesn't matter how much water i drink i still feel my mouth needs more but i don't think i'm dehydrated.
Same for me. I can vape lots of zero nic juice and don't get a dry mouth no matter what the PG/VG content. The more nic in it the more my mouth feels dry.
But that is not dehydration.
