Zopiclone 7.5 withdrawal I have been taking zopiclone at night for releif of anxiety and sleep for?

According to Drugs.com the following is noted:

If you stop taking Zopiclone tablets
•Treatment should be gradually withdrawn as the symptoms you are treated for will return more intense than before (rebound insomnia), also anxiety, restlessness and mood changes may occur. These effects will disappear in time.
•If you have become physically dependent to Zopiclone tablets, sudden withdrawal of treatment will lead to side effects such as headaches, muscle pain, extreme anxiety, tension, restlessness, confusion, irritability. In severe cases other effects may appear, such as hypersensitivity to light, noise and physical contact, abnormally acute hearing and painful sensitivity to sound, hallucinations, numbness and tingling of the extremities, derealisation (feeling the world around you is not real), depersonalisation (feeling your mind is becoming separated from your body) or epileptic seizures (violent fitting or shaking).

You need to taper off this medication over several weeks time reducing your nightly dosage by 2.5 mgs every week to 10 days. This should prevent serious withdrawal effects such as seizure. Rebound insomnia and anxiety, restlessness and mood changes may last a couple of weeks, but will be less if you taper slowly.
