Ingredients to Keep in Mind
Every drink is delicious, but there are a few things to keep in mind:
- 30–60 mg of caffeine can be found in Coke or Dr. Pepper
- Artificial colors and flavors: Slushes and flavored waters contain these
- High fructose corn syrup: Often used in sweetened drinks
Sonic’s Ice and Drink Volume
However, it does occupy some drink space. This can cause the actual liquid content of some drinks to be slightly less than 32 oz.
But this ice keeps the drink cool and balances the sweetness—especially in slushes.
