The drink that's worked up to first place on my list is green tea. I've always kept some in the cupboard, but a coupla years ago I tried the bottled stuff, sweetened & citrus-flavored. It's a great drink, but a little expensive for my budget, so I started brewing my own & adding sweetener along with a drop of lemon flavoring. Even my additions fell by the wayside as I would get in a hurry & just drink it plain. Now I don't even drink it HOT . . . it's good hot OR cold. Full of antioxidants - low in caffeine. (it isn't NON-caffeinated, but doesn't have much)
