Acupuncture for insomnia is usually effective in 3-5 sessions. For example, the patient may have drowsiness during acupuncture, but after starting the acupuncture, he or she cannot sleep again at night. By 2 weeks later, the effect will be more obvious. Therefore, according to clinical observation, the course of acupuncture for insomnia is usually 15-20 days, and if it is not good after 15-20 days, the next course of treatment will be carried out after 2-3 days of rest. In general, 1-3 courses of treatment for insomnia are basically possible, and in many cases 2 courses of treatment are possible, and then with other treatments will be better faster. If there is no effect at all by the 3rd course, we should consider whether there is a problem with the treatment method and whether there are other diseases affecting sleep. It is not possible to continue with the 4th or 5th course of treatment, which may affect the patient’s treatment.
