You must have been in a situation where you fall nausea, and that you do not have a drug that would help ease the discomforts. The good news is that you do not need a cure, because there is acupressure.
In fact, whether you sick with a cold or harrassing you a hangover, by pressing a point on the inside of the upper arm, just below the palm, will help you to prevent vomiting.
Find a point P6, and press it with your thumb or fingers. Its stimulation sends a signal to the brain and the body begins to release certain neurotransmitters, such as serotonin, dopamine and endorphins.
These neurotransmitters will change the chemistry in your body and you will not feel sick neither you will vomit.

Acupressure is a method of traditional Chinese medicine (and one of the methods used in physical therapy), pressing with your fingers or aids in particular (acupressure) points on the body in order to help yourself or others.
Name of acupressure is a Western origin, and means “stabbing”, pinch and swipe or aids to a certain point (which the Chinese called acupuncture points) on the body. Acupressure by the experiences of traditional Chinese medicine, is balancing life energy (Chi) and bio-energy, which results in healing or rehabilitation of certain diseases or ailments.
