For those that say they like the sweet tea but they can't handle the sugar, I have a suggestion: start cutting back. All you need is a dedicated measuring cup for sugar. Each time you make tea, use slightly less sugar. If that's too fast for you, each week cut back.
Before we moved and I started having to use well water, I was putting 1/8 cup of sugar in a gallon of tea. I loved it. Hubby doesn't care for really sweet tea, so it made us both happy. Now I filter my well water with the filter pitcher (whole house filter is $$$ away in the future). Currently I use a 1/4 cup measure and shake some of the sugar off/out for 1/2 gallon of tea.
BTW, both of my parents have Type 2 Diabetes. My FIL has Type 2 Diabetes. This means my poor children have three grandparents with adult-on-set diabetes. I'm trying to teach and practice moderation. Go ahead and have something sugary, just don't eat the whole bag of candy, don't eat the whole cake, etc. Slowly cutting back on the sugar in our tea is one way we can enjoy the sweet drinks and practice moderation.
Oh, does anyone else have a dedicated tea pot? I don't mean the thing you boil just water in. I mean for boiling the tea bag in. A few years ago my Dad went and purchased his own tea pot. It's a small pot others would warm vegetables in for a meal. Do not EVER make the mistake of grabbing Dad's tea pot for beans or corn. You will not hear the end of it!
