Two liters of water a day should keep you well hydrated. You can start with eight ounces of water every morning, which would provide you with the adequate hydration necessary to start the day.
If you don’t like drinking plain water, you can add lemon, berries, or cucumber slices. You can also add 5ml (a teaspoon) of diluted apple cider vinegar to 300ml of water. This will help lower your blood sugar levels. Adding sweeteners, artificial flavors, Kool-Aid, Crystal Light, or Tang is not recommended.
Also, try to avoid sparkling drinks. You can drink a maximum of just 300ml a day, but sparkling drinks may make you feel hungry, and the CO2 in them will irritate your stomach mucosa.
