I drink unsweetened and un-lemoned (I tell them “lose the fruit!”) tea too. Brewed Lipton is great...that Nestea crap some of the restaurants serve down here in South Texas is NOT tea! It’s just nasty! I don’t use sugar of any kind, in anything. It gives me a such a sugar high that I get all jittery and then I crash and want to go to sleep, I just can’t handle it.
I think I’ve never had a weight problem because I drink unsweetened tea instead of Coke (or sodas).
