Higher dosages were associated with longer sleep latency and delays in reaching deep sleep. Chronic users (≥3 times per week for >3 months) experienced poorer overall sleep architecture compared to those with insomnia who were not taking the drugs. Users with higher dosages needed more time to fall asleep and took longer to reach deep sleep. For older adults who are chronic users, he recommends a gradual decrease of benzodiazepine consumption over several months, coupled with a cognitive behavioral therapy for insomnia program. A psychological intervention can help achieve a successful withdrawal from these drugs and improve sleep quality,” says Dang-Vu.
