Dehydration Symptoms

Just curious, but has anyone ever noticed that their tongue gets a greyish tint when they become dehydrated? I have noticed this and wondered if I am just a color changing weirdo or if others have the same thing.

My daughter has experienced this when she’s forgotten her DDAVP and gets really thirsty, which coincidently she did yesterday! She told me that her spit was like jam!! ewww.

Drs say I am not dehydrated when I have no spit,my gums get sensitive and swollen,and tongue looks grey-white.My face is like tanned leather around the mouth area,and tongue tip gets numb. Anyone else?

One more comment how is everyones memory? Mine is terrible and concentration too. Also mood swings,not a good disease , and no real experts have helped me.I can’t find a dr with many patients with DI and experience.
