I like water, our from the well is especially good, so I can't help with the powder things.

Get some plain seltzer/sparkling water and mix with some fruit juice or maybe those Kern's Nectars. It's what we did when we lived in the low desert and had to drink a gallon + of fluid a day to stay hydrated. After 2-3 quarts even a guy like me that loves water had to do something to get the rest of the gallon a day in me.

Now, I probably drink a minimum of a half gallons a day as it is in the high desert.

The desert is a true treasure for him who seeks refuge from men and the evil of men.
In it is contentment
In it is death and all you seek
