Lunesta 3mg (eszopiclone) is the highest common dose prescribed for adults with chronic insomnia. It works by calming brain activity, helping users fall asleep quickly and enjoy uninterrupted rest. Doctors typically recommend this dosage for patients who do not respond to lower strengths. To minimize risks of next-day drowsiness or dependence, Lunesta 3mg should only be taken as directed by a healthcare provider at bedtime.
