Thanks for using Healthcare magic.
I have gone through your available history.
If the insomnia is associated with Stress or depression
, in my opinion zopiclone alone will not be sufficient.
You should go for detailed psychiatric evaluation and should get treatment for stress/Depression in the form of either pharmacological or psychotherapy
meanwhile you can try relaxation therapy
, Yoga or self motivation to get rid of stress.
I hope you will be fine soon.
