Thanks for the reply. I should have mentioned I drink about 2 liters of water a day in the original post. Lower flavor could be key. I wonder if my nicotine level could be causing it too? I only get 12-16mg nic in my liquids.
Not sure if it is dehydration if you can vape non-fruity flavors.... But to comment, 2 liters of water is the the recommended minimum an adult should intake daily. So if you are doing activities that can dehydrate, consider drinking more water.
