I went primal back in March of this year. My energy has increased, greatly! I still have MS fatigue (lassitude) that hits me in the afternoons, and since going Primal, this has been relieved, mildly. I still have issues with my legs not always getting the message my brain sends out, resulting in falls! OTOH, I've lost 14 lbs, my digestion has never been better! I'm staying on this Primal path. It seems to be good for me.
