Lunesta (eszopiclone) is a prescription sleep aid designed to help adults fall asleep faster and stay asleep longer. Compared to Ambien (zolpidem), Lunesta’s effects typically last longer, making it ideal for those who wake frequently during the night. It works by calming brain activity, promoting restful, uninterrupted sleep. Common side effects include a metallic taste, dizziness, and next-day drowsiness if taken without sufficient sleep time. Buying Lunesta online from a licensed pharmacy offers convenience and privacy, but a doctor’s prescription is essential to ensure safe use, proper dosage, and to avoid interactions with other medications or alcohol.
