If you feel bad due to cold or hangover than press the point on the inside part of your upper arm, right under the palm, and this move should prevent vomiting.
Find this spot and press it with your thumb or finger. With stimulation you send signal to your body and brain and the body starts to create certain neurotransmitters such as serotonin, dopamine and endorphins.
Those neurotransmitters will change the chemistry in your body so you won’t feel nausea and you won’t have the urge to vomit.
