Hi Micah,
Maybe this might help you forget the fast food Shake. I doubt it, but it is a shake of sorts and only has 100 calories.
Vanilla Shake
(makes 1 serving)



1/3 cup frozen low-fat, sugar-free vanilla yogurt
1/4 cup crushed ice
1/4 cup skim milk
1/4 teaspoon vanilla extract

In a blender, combine the frozen yogurt, crushed ice, and milk, turning the machine off and on several times until blended, about 1 minute.
Add the vanilla. Blend for another 30 seconds.
Pour into a tall glass and serve with 2 straws, if desired.

Enjoy!
