Dr. Eric Weisman answered

Specializes in Neurology

Drink water: Too much water can be bad. You can dilute your electrolytes. Like I said earlier 8 glasses of clean fresh water. At some point you will acquire a taste for good water. It's refreshing when cold . The brain and kidneys just live it. Did you know humans are made of 70 percent water ?
