Because They Were Hammered by 7UP

The new C2 (faux low carb soda) from Coke was a dismal failure (still too much sugar) because the folks at Cadberry Schweppes came out with 7UP Plus that has Splenda and fruit juice. For diabetics, like me, it's heaven sent. It's actually even better than Diet Rite (also with Splenda) and Hansen's (except for the root beer which is great).
