How can you make someone vomit?

Making someone vomit requires a combination of physical and mental actions. The physical process includes placing a finger down the throat and / or giving them an enema. To accomplish this, have the individual place their tongue flat against the back of their mouth so that they do not choke on any excess vomit, then slowly guide it out of their mouth. Additionally, providing stimulation to the area around the bellybutton via gentle pressure or massage may also bring about nausea and thus induce vomiting as well. 

The mental action involves hypnotizing words and suggestions intended to make someone feel sick and want to purge. For example, using words such as "nausea", “queasy”, “dizziness” and other related descriptions will encourage thoughts associated with feeling ill in hopes that vomiting will follow suit. Repetition of these ideas reinforced by verbal commands is key here - this allows the person to surrender control over their body leading up to feeling ill enough that throwing up becomes inevitable.</p>

Gastric lavage is one method to make someone vomit, which involves using a tube inserted down the person's throat to wash out their stomach. This procedure should always be carried out under medical supervision.
