I recently came of zopiclone after months of being on it. I'm 25 day sober from alcohol but was using zopiclone as directed for sleep. Unfortunately, the zopiclone started causing me severe anxiety, it started in the mornings when I woke up and lasted all through out the day, so I was prescribed adivan for a short period but that didn't work either. It was horrendous. I wanted off so bad, but I also wanted to sleep. The problem with zopiclone is it has a very short half life, like 5hrs so my body was going through withdrawal shortly after taking it. Long story short, my Dr. took me off zopiclone and adivan and put me on mitzipine and a dose of clonazepam for 3 weeks and so far it seems to be helping. Still have massive anxiety from coming off the zopiclone after 3 days but it's gotten alot better.
The Valium should help ease the withdrawals and I suspect after 7 days you should be feeling much better.
