Unless a doctor says otherwise, consider adding some salt back into your diet. A bouillon (stock) cube mid-morning, mid afternoon (2-3 grams) can make a difference.
Why?
From the book The Art and Science of Low Carbohydrate Living (Volek):
Page 20, 150 and 240: "Salt deprivation leads to light headedness, fatigue, headache and malaise."
"... the body responds [to sodium restriction] by contracting its circulating volume... [which is what] causes dizziness, headache, and ease of fatigue."
"... the amount of carbohydrate in our diet changes our need for salt. High carb diets make the kidneys retain salt, whereas a low carb intake increases sodium excretion by the kidney ('called the natriuresis of fasting')."
