I often felt that plain water didn't quench my thirst, and my mouth felt dry even right after drinking. The remedy I use now is a small lick of Celtic Sea Salt (the French grey stuff) before drinking a glass of water. No more dry mouth and, surprisingly, sleeping longer hours before having to get up for a bathroom break. I've also started using that salt in salads etc.
