If you water isn't floating you boat (LOL) you can try a couple of other options. These options will allow you to continue to reap the benefits of drinking water, while pleasing your taste buds at the same time.
Add lemon or lime to your water to amp up the flavor a bit. You can also opt to add a teaspoon of agave nectar to give the water a bit of sweetness if you feel it is lacking a bit. Herbal teas like Pau D Arco are also excellent; allowing you get your water needs filled, while providing a nice, light sweet taste and some antimicrobial benefits.
Finally, you can also try coconut water, which is excellent for hydration and is also high in electrolytes like sodium and potassium, two of the most vital minerals in nutrition.
