A new experimental vaccine that aims to cure alcoholism will give anyone who has been vaccinated an immediate and head-splitting hangover after just one sip of booze.

According to the Daily Mail, scientists at the University of Chile have spent a year developing the experimental drug as a way to combat alcoholism.

The shot is effective for about six months to a year and works by speeding up the hangover process.  The vaccine works by sending a biochemical message to the liver to stop it from expressing the genes that metabolize alcohol.

The liver normally turns alcohol into acetaldehyde, a hangover-inducing organic chemical compound that is then broken down by a metabolizing enzyme.

If a person who's received the shot tries to drink alcohol, they will almost instantaneously experience severe nausea, accelerated heartbeat and general discomfort, according to the Daily Mail. Essentially, the vaccine shot is to get alcoholics to associate drinking with bad side-effects and misery instead of fun, relaxation or as a way of coping with life problems.
