My brother-in-law is a CANCER survivor. He has had HIS SALIVARY GLANDS, part of his tongue and palate removed and radiation treatment. HE CANNOT GO ANY TIME BEYOND A FEW MINUTES WITHOUT WATER. He walks around with it at ALL times. His body has no other way to wet his mouth and throat. But you wouldnt know it to look at him.

WATER IS MORE THAN "MEDICINE" FOR HIM. WHAT IS HE TO DO??
