I like flavored water, sparkling water, green tea, and have tried a few of the infused water recipes. I really do not like water infused with anything citrus as it gets bitter.
I recently found a really good clearance deal on some of the Soda Stream Ocean Spray diet syrups. I like the cranberry and and the raspberry cranberry added to plain water or seltzer water. But, if you are trying to avoid artificial sweetners they are in most of these things including Mio, Crystal Light, the Soda Streams and even some of the fizzy waters, club sodas, tonic waters and definitely the flavored sparkling waters. I personally can handle the ones with Splenda (sucralose) like the Soda Stream and Mio but not a fan of the aspertame variety like Crystal Light. I don't like it and it doesn't like me, either.
