Polar seltzers are the best! I sometimes get really bored of dull, plain water, so I like a little bubble water once in awhile. Best part of these calorie- free beverages is there are no artificial sweeteners. These days it's really hard to find a flavored water or seltzer that doesn't have artificial garbage in it. They're flavored lightly and sweetly, with no gross aftertaste because of any artificial sweeteners. They're super affordable, a lot of stores carry them for less than $2 and usually run sales that make them 10 for $10. Wide variety of flavors, too!
