Are Slurpees sugar free?

But there's good news for those watching their waistlines: 7-Eleven just announced plans to sell the new Slurpee Lite. The new drink is the first national sugar-free Slurpee made with Splenda.

Are Slurpees bad for you?

Consider your Slurpee a summer indulgence, not just another drink. In an average 11-oz slurpee (the size 7-Eleven is giving away on July 11th), depending on flavor, you'll get around 175 calories, 48 grams of carbohydrates (more than the average person should be consuming in a day) and a boatload of harmful chemicals.
