Iced tea?

I make 2 qts a day in the summer. Boil 6 cups of water, add 3 tea bags and a heaping 1/2 cup of raw sugar, steep till cool then fill with cold water. I fast till lunch and only drink water till then. After lunch I eat and drink what I want. I do my best not to eat or drink anything man made.
I do the same, except I use a smaller amount of powdered sugar. My A1C was 4.8 my last blood draw. I stay away from soft drinks, diet or otherwise. I'm 63.
