Interesting... After going Primal my night sweats completely vanished. Same for my wife.
Also very low body odor in sweat and "bad breath"/ morning breath. I attribute this to such a low sugar intake.
try to reference David Wolfe's book on Superfoods, I believe one of his superfood suggestions addresses low estrogen. FWIW I have read the book, but have not acted on his preaching yet. Ok, I'm down with dark chocolate already
