Every once in a while I get sick of plain water, but the flavored waters here in Germany are either full of sugar or artificial sweeteners.
I found out how to make my own 0 calorie flavored water threw accident!
We have great fruit teas here in germany, I use 5 bags of fruit tea on a pitcher of hot water and just let it cool down. Then I mix it with sparkling water and finished. Flavored Water!
My favorites are blueberry vanilla or black and blueberry fruit tea from Teekanne.
