I've recently started putting cinnamon in my coffee, too. I use only a tiny amount of sugar in my coffee (just to take the edge off), so made a mix of Ceylon cinnamon and a little sugar, and I sprinkle that into my coffee rather than just plain sugar. I don't drink a lot of iced tea, but I bet cinnamon adds a nice edge to it. I just bought a bottle of "higher quality" vinegar to take after dinner to try to quell my occasional acid reflux. I also bought a jug of Aloe juice to try in the morning to keep my digestive tract in order. If nothing else, I should soon have a patch of wonderfully medicinal grass growing over my drain field
