I'm really glad you're back with us, Doin. :)
You will probably feel quite rough. Zopiclone is powerful stuff and you took too much of it. Please don't take any more.
You will prob get some withdrawal symptoms, which could be quite bad because you took so much, but shouldn't last long (a couple of days) unless you have been taking it for a while.
Here's what the NHS Choices website says can be the withdrawal symptoms:
"These include headaches, musclepain, extreme anxiety, tension, restlessness, confusion, irritability, rebound insomnia, tremor, sweating, agitation, palpitations, faster heart rate, delirium, nightmares, panic attacks, muscle cramps and gastrointestinal problems. If withdrawal is severe the following may occur: derealisation, depersonalisation, numbness and tingling of the extremities, hypersensitivity to light, noise and physical contact, hallucinations or seizures".
Like I said in my PM, I do think you need to get yourself checked out. Can you get a taxi to A&E? Tell them everything, if you can face it. I mean everything that has been going on with DD, as well as all the medication you've taken.
If you can't face A&E, here are some other places you could try...
Your GP (except you said they were useless... :( )
