Hahaha, look at that old post from me back in 2009! Here I sit having an (unsweetened, of course) green tea! I don't take milk or sugar in anything except Earl Gray or Lady Gray at work sometimes, cause we don't have a kitchen downstairs and due to my back I can't always make it upstairs so I have to cope. I also just bought my first Pu-erh so we will see how that goes. It smelled odd but tasted great. Hmmmm, I am pretty sure I have fallen down the slippery slope.
I mainly drink black teas and with new ones I do try without sugar, but I almost always end up adding a tsp. I have a sweet tooth and to me it just enhances it. Iced tea without sugar would kill me though. Would be much healthier but I hate unsweetened iced tea (from standard teabags)
