A gadget that helps me to drink more water is my Sodastream. It adds carbonation to beverages, even water. I used to spend a lot on carbonated bottled water, but now I can make it at home. I don’t feel guilty about drinking it because it’s just water.
You can also make your own soft drinks with Sodastream. They offer more than 25 regular, diet, energy and caffeine-free flavors of syrup (sold separately). Each 500 milliliter soda mix bottle makes the equivalent of 12 liters of soda (about 33 cans). The regular soda mixes contain no high fructose corn syrup, while the diet soda mixes contain no aspartame.
