Hi there, thanks for asking. It is a great step that your chronic insomnia
is controlled with zopiclone
(for some people it is not controlled with even medication). The next step is to change a little your style of living in order to be able to gradually discontinue the medication. It means you should read thoroughly about sleep hygiene
(this is a link from University of Maryland which has mentioned the important point: http://www.umm.edu/sleep/sleep_hyg.htm). I am sure that you know about most of them, but it is good to have a review. The next step is to use behavioral methods which are stimulus control and bed restriction (not to stay more than 20 minutes in bed whenever you are awake, in the middle if the night or in the morning). About two third of people find the ability to decrease gradually zopiclone after two to three months of practicing sleep hygiene points and behavioral methods. One third of people need to take advantage of cognitive therapy
for insomnia and eventually find the ability to wean off the medication. It could be done by a therapist who knows about CBT for insomnia or even any other psychotherapist. I wish you a good health.
