To stop taking zopiclone and ensure that you can sleep well afterwards, it is important to gradually reduce the dose under the guidance of a pharmacist. You can also try non-pharmacological methods to improve your sleep hygiene, such as turning off screens before bed, maintaining a consistent sleep schedule, and creating a calming bedtime routine. It may also be helpful to seek therapy from a psychologist or therapist specializing in sleep disorders. Remember to take it one step at a time and be patient with yourself as you make changes.
