Place blueberries in an ice cube tray, fill it with water, and place it in the freezer to chill overnight. When symptoms occur, fill a glass with 4 oz of water. Drop in 2 Alka-Seltzer® Original tablets and let them fully dissolve. Then, add your pre-made frozen blueberries to the glass. Finally, add the garnishes to the rim and drop in amount of ice cubes desired, and drink up!
