Mods -- sorry if this is the wrong forum -- but I knew folks here would want to see this.

Most 7-11s have added Sugar free Slurpees.
They come in two varieties:

• Crystal Light
• Diet Pepsi

The Crystal Light is advertised as being 50 calories per 8 oz serving (and something like 9 carbs).
The Diet Pepsi is advertised as being 0 calories per 8 oz serving (and has "0" carbs.)

For those of you who may have been wondering, I asked the Manager to see the Ingredient List.

Crystal Light has Glycerin, Sorbitol and Maltodextrin as it's main ingredients.
The Diet Pepsi has Erythritol.

There's plenty of other artificial colors and such, but I did want to let you know that both have tons of sugar alcohols, which will likely provide a Slurpee Laxative effect, and may stall your weight loss.

However, if it's really hot, they're both pretty good for a treat once in a while.
