Hiccups can usually be stopped by simple methods such as distraction, holding your breath, drinking water, sneezing, straining your tongue or being frightened, but it usually takes several repetitions to stop them. You can also stop hiccups by covering your mouth with a plastic bag and breathing in it for a period of time, or by pressing on your eyeballs or supraorbital nerve. However, it is important to note that the above methods are only suitable for people with mild symptoms, who are in good health and do not have serious cardiovascular disease.
