Over the last decade I have suffered from severe sleep deprivation and daily brain fog. That is, I did, until I learned about adrenal fatigue. A ketogenic diet has erased my symptoms almost entirely. I no longer need bottles of soda (and all that deadly sugar) just to get through the day. This was added relief, as I was, at the same time, being told I was prediabetic. No more do I fear falling asleep on long drives or at the dinner table!
