My Doctor wants me to drink 80oz of water each day, at first that was a real challenge but my daughter told me about True Citrus which is small packets of crystallized fruits that you add to your water. I know it comes in four flavors, Orange, Lemon, Grapefruit, and Lime. My favorite is the Lime it is available on Amazon and I add one packet to 20oz of water taste great and really helped with my water intake. Ended up getting 500 packets of the lime for around $25. This has zero sugar and nothing added worth a try if you were like me and really struggled with the amount of water I have to drink.
