Water Be sure to stay well hydrated throughout your fast. Water, both still and sparkling, is always a good choice. Aim to drink two liters of water and other fluids daily. As a good practice, start every day with eight ounces of cool water to ensure adequate hydration. Add a squeeze of lemon or lime to flavor the water, if you wish. Alternatively, you can add orange slices, berries, or cucumber slices to a pitcher of water for an infusion of flavor. Diluted apple-cider vinegar in water may help lower your blood sugar. However, artificial flavors and sweeteners are prohibited.
