Yes Water, occasional black coffee, occasional water with some electrolyte powder. Daily: Bayer One a Day Multivitamin A few times a week: Berg's Nutritional Yeast (Vitamin B) Berg's Electrolyte Powder Even though his information seems to be good and I like some of his products, Dr. Berg bugs me - his approach and personality comes across like a scammer to me. His being a chiropractor does not aid in my opinion of him. By a huge margin I am more of a fan of Dr. Jason Fung. Fung is an actual physician whose specialty lead him to this niche. I highly recommend Dr. Fung's books.
