We usually recommend starting a clear liquid diet the morning prior to your exam. In general, you can drink any clear beverage, but we recommend avoiding anything with artificial colors, especially red green or blue. Also carbonated beverages may worsen your prep quality. If you cant see clearly through the liquid and read a newspaper through it, you probably shouldn’t drink it.
