Yep. this is what we use at my house. There are a couple of soft drinks out that are sweetened with splenda. One is DIET RITE. The other is a punch-type drink that comes in several herbal-enhanced flavors. Both of these beverages are VERY good, and very tasty. If you are looking for a summer refresher that doesn't add calories, check for these.
Can you still get Diet Rite? We can't get it in Seattle. We were told that Royal Crown went out of business and Coke and Pepsi were fighting over the rights before they would release Diet Rite again. Hanson's uses Splenda and is very good, but we miss the raspberry Diet Rite.
