Is Memory Loss Common Symptom While On Zopiclone With Antidepressants?

I have been on Zopiclone since last week as I am currently on antidepressants and suffering from insomnia. Part of the symptoms I have is memory loss and I thik I have taken 3x 7.5mg tablets as I don t remember taking them....is this going to be dangerous? I started them last Monday and haven t used them every night-nor have I been drinking alcohol. Am I going to be ok?
