Abstract: FIELD: medicine, narcology. 
     SUBSTANCE: the present method deals with forming negative conditioned reflex to alcohol due to hypnosis, impact onto reflexogenic areas and coding. Moreover, all the stages of therapy should be carried out individually by applying nondirective psychotherapy at every stage by making samples for disgust or neutral attitude to alcohol. At the first stage of therapy, one should perform individual psychotherapy directed for positive formulation of positive therapeutic result by a patient. Then comes a seance of nondirective psychotherapy and placebo-procedure to detect alcoholic dosages. At the second stage, one should perform individual psychotherapy directed for revealing the perspectives of new behavior, again it is necessary to carry out the seance of nondirective psychotherapy. At the third stage, one should conduct the seance of individual psychotherapy to detect new feelings in a patient followed by the seance of nondirective psychotherapy. At the fourth stage, after carrying out the seance of nondirective psychotherapy one should teach a patient to apply autogenic training directed for maintenance of desired state: a patient has the task to use alcohol at the dosage indicated by a patient at the first stage of therapy. Next day, at the fifth stage of therapy, one should control patient's feeling followed by the séance of nondirective psychotherapy, coding the dosed alcohol intake at the dosage indicated by a patient at the first stage of therapy, due to hypnotic impact by applying an aggressive phonogram with possibility to remove the code by a patient himself/herself. Simultaneously, it is necessary to affect cerebral reflexogenic areas with impulse current and closed eyes with light impact, and, also, the impact with odor. Then comes the task for a patient to drink alcohol in the dosage indicated at the first stage of therapy for 2-4 mo and perform maintenance therapeutic seance and that of autogenic training. Moreover, reflexogenic impact should be performed for the following cerebral points: Bai-khuey, Bai-shen', Chen-lin, Nao-kun, Pan-lyan'-tsuan'. Code removal should be fulfilled due to an inert safe substance as a capsule or a tablet of strange shape and color. Seance of maintenance therapy and autogenic training should be carried out with the help of laser disc or audiocassette labeled with the same odor applied earlier during patient's coding. 
     EFFECT: higher efficiency of therapy.
