Wednesday is SlurpFree Day at 7-Eleven Stores

Slurpee fans can get their brain freezes and sugar highs for free on May 23.

Participating stores in the chain are giving away free, 7.11-ounce cups of the popular frozen drink on Wednesday, "SlurpFree Day," from 11 a.m. to 7 p.m. to celebrate the beginning of the summer, the official Slurpee season, 7-Eleven officials in Dallas said Tuesday.

If you want the brain freeze without the calories, there's the new Slurpee Lite Fanta Sugar-Free Mango drink. The Slurpee Lite Fanta debuted this month and is the first of several sugar-free and regular flavors this summer, according to a 7-Eleven news release. 

The 8-ounce Slurpee Lite Fanta Sugar-Free Mango drink contains 20 calories, compared with the 66 calories in a Slurpee Fanta Wild Cherry of the same size, according to 7-Eleven headquarters. Here's a Slurpee-flavor debut time line for all the fans out there:
