First off, please don't get dehyrated. The following is from a World Health Organization pamphlet:
"If ORS [Oral Rehydration Solutions] are not available, mix 6 teaspoons of sugar plus one level teaspoon of salt in one litre of safe water («taste of tears») and drink as indicated in the table."

Other sources, including other World Health Organization sources, recommend only half a teaspoon of salt per liter (~ 34 ounces). So, underdo the salt, let's say 2/3's a teaspoon. For me, like when I've been moving all day and am hot and dehydrated, drinking gatorade makes me feel worse. I think it's so concentrated it sits in my gut drawing fluid from the rest of my body, like drinking sea water. A friend who plays softball recommends half gatorade, half water. I could almost see going with one-third gatorade, two-thirds water.

I have experienced and struggled with bouts of depression. What I have read is that the first antidepressant may not work but a later one may, that it's trial and error in a respectable sense. And my guess is that it's largely the same with anti-anxiety medication.
