Insomnia is a sleep disorder characterized by difficulty falling or staying asleep. It can lead to fatigue, mood disturbances, and impaired functioning. Zolpidem, commonly known as Ambien, is a medication that helps alleviate insomnia by promoting relaxation and sleep. Taken as prescribed, it aids in establishing a regular sleep pattern, allowing individuals to achieve restful sleep and improve overall well-being. Always consult a healthcare professional before starting any medication.
