Insomnia and dreaminess require the selection of appropriate medication depending on the situation. If benzodiazepines with sedative, anti-anxiety, inotropic and anticonvulsant effects are used, including eszopiclone, fluazepam, alprazolam and diazepam, they can shorten the sleep latency and increase the total sleep time. Melatonin agonists can also be used to treat insomnia with difficulty falling asleep as the main complaint, as well as circadian rhythm disorders, but they are generally only used under medical supervision. Chinese herbal medicines or herbal tonics can also be used to regulate treatment.
