Would you please refer me to some reading material regarding the link between aldosterone and dehydration? I think this may be my problem. As a self-employed consultant and long-time single parent, I have been stressed for many years. I have been self-medicating, and feel much better. But I can't hold onto water; I am always dehydrated, but not really thirsty. My fingers are always wrinkled, circulation is poor, blood pressure is low, and my fingernails have horrible ridges in spite of a healthy diet.
