Most of my water consumption is from caffeine free fruit iced tea. I add 3 packets of Truvia per 96 ounces for a little extra sweetness. Sometimes I add 2 green tea bags to the mix. I have a tea maker and make 3 quarts per batch. It doesn't last long.
My favorite flavor of fruit tea...Bella Coola
For a change of pace, I will also make limeade and lemonade by the 16 oz glass using a healthy splash of the RealLemon/Lime concentrated products.
Half a packet of Truvia is plenty for that.
And then of course there is Coors Lite...
