Is it ok to take Zopiclone during the day? Would it cause a problem?

I think so. You're only 18 yr old and taking morphine (? dose) and diazepam (? dose) as well. Zopiclone is indicated short-term for insomnia and cross tolerant with benzodiazepines/ addicting if used long-term. I'd say using Zopiclone during the day for you is fueling an addiction. Are you being honest with prescribing doctor? Please consider treatment to get off these drugs with medical supervision.
