I have lived in NC all my life, and can remember when only SWEET tea was served. Now, because of diabetes and the influx of non-North Carolinians, all restaurants serve both sweet and unsweet tea. Around here, there used to be a reastaurant that served only unsweet...but it wasn't open very long(wonder why?) I make mine the way my great-grandmother and grandmother did. The old-fashioned way is to boil a large pot of water on the stove(at least 1/2 gallon to about 3/4 gallon of water), drop in 3-4 large family-size tea bags(Luzianne and Lipton are the more popular brands around here), and let them "seep" (or sit) in the water for at least 5 minutes, but no more than 30 minutes(as the tea still needs to be warm when you add the sugar). Remove the tea bags, and pour the tea into a gallon-size jug, add 1 to 1.5 cups of sugar(some folks use up to 2 cups, but I would go into a sugar coma if I used that much), and finish filling the jug with cold tap water, stirring as you add the water. I have to admit, I HATE the strings on the tea bags, and only one supermarket used to sell the Luzianne round(stringless) bags. Now I buy the gallon-size tea bags at Sam's Club(Lipton 48-count), so I only have to use 1 bag per gallon of tea. Since I only make it in gallon jugs at home, this works fine for me. When we go to Disney, I buy a box of the family-size tea bags to take with me, as the pitchers in the DVC rooms are only half-gallon size. The first thing I do when I get to the room is to call housekeeping for a second pitcher, and boil a large pot of water. I make a jug of sweet tea and a jug of "splenda" tea for DH(who is diabetic) immediately, then replenish as needed using 2 tea bags and a little less water for the half-gallon pitchers throughout the week. The real secret to "southern sweet tea" is that we add the sugar while the tea is still hot, so it dissolves completely. And we are not afraid to use too much sugar, either!
