Hi I also have tried the Crystal Lite slurpees, I didnt really like them they had a very strong aftertaste and a stong fake sugary flavor. The other day I noticed a orange pineapple one which was slightly better. I also think that the 11 carbs are from sugar alcohols because regular Cystal Lite has no carbs. Athough I personally think a Diet Coke slurpee would be perfect! I would seriously get a slurpee everyday if that flavor was added. With diet coke there are no calories and no carbs-much better that Crystal Lite and of course much better tasting. I have already e-mailed 7-11 and if anyone feels so inclined to do so to it couldnt hurt! Just imagine FROZEN DIET COKE!!!
