Since going primal a week ago, I've been constantly thirsty. Before going primal I was rarely thirsty. As soon as I finish a glass of water I'm getting another. In my whole life that has never happened. Is something wrong wih my diet? I went primal to loose weight and have been eating my base metabolic rate in calories but limiting my carbs to under 100. Many days this past week I've been under 50 grams of carbs.
