[Apropos of a case of sleep hypochondriasis]

About one case of an important sleeplessness for 4 years, the authors show the characteristics of this moan, which they would want to call it "Sleeping hypochondria". This hypochondria is very "efficient" because the sleeping quality is always subjective. More, patient and therapeut especially invest it. Oftenly, hypnotics are ordained. In this case, the confusion between offered and real symptoms could be grown. In fact, the last one is the patient moan, his speech subject. The treatment of this particular case, by paradoxical injunction, allowed to create a breaking of the patient system. The paradoxical cure, by made-self prescription, allows to understand much better the "insomnia work" in the aggressive relationship with the therapeut.
