I agree. Too much water can "wash you out." It can screw up your gastric juices/dilute you too much (sodium/chloride levels and electrolytes get unbalanced which is dangerous!).
I drink unreconstituted organic veg. broth and use tons of sea salt. The veg. broth has at least 4 times more sodium than the Gatorade. I literally eat salt and feel a lot better now.
So, I take all with more than a tsp. of salt. I love pickling my own fruit, too.
