What happen if you take 30 zopiclone?

You die

It depends on which anti-depressants, but the effects will never be good. Depending on the drug, it could cause anything from death to a coma. In any case you would have to be taken to hospital....

Most likely your liver will fail and you will either die or have to live the rest of your life being kept alive by machines. So dont do it.

Seek medical attention immediately; this amount would likely cause heart attack or stroke along with psychosis.

Unless you have use it when it's really, really cold outside - nothing.
