To prevent a hangover:
Many people find one to two glasses of water taken with AfterBuzz at the end of the evening, and one to two glasses of water with AfterBuzz the following morning is sufficient. One may also alternate one glass of AfterBuzz in water with every alcoholic drink consumed.
To knock a hangover:
Mix 1/4 teaspoon (20 drops from the 25 ml-bottle) of AfterBuzz with 16-ounces of water. Drink. Repeat one to two hours later. You should notice an improvement within 15 minutes of drinking the first glass.
