Vomiting can provide instant relief in some cases, though it is never recommended to force vomiting if you are feeling okay. This only applies when someone is always over-indulging in huge amounts of food or alcohol, or when they have swallowed something toxic (in the case of poisoning).
Vomiting is a natural defence mechanism that the body uses to get rid of toxic substances. It is supported by years of study, but you should only induce vomiting if you are aware of the dangers and risks associated with it not being done properly.
