Posthypnotic suggestions are used to achieve an effect beyond hypnosis, which thus acts post, after hypnosis. A posthypnotic suggestion is a suggestion that takes effect only after hypnosis. It is given under hypnosis, more precisely in a trance, but it becomes effective only after hypnosis. In most cases, the goal is to achieve the effect only after the hypnosis. This is the case, for example, when quitting smoking, treating pain or forgetting memories. Posthypnotic suggestion is often used to achieve an effect that goes beyond hypnosis - that is, it works post, after hypnosis. An example of this could be "whenever you are standing at the refrigerator, remind yourself to really eat only what is really good for your body".
