insomnia
"I finally decided that I'd suffered with insomnia for long enough and my doctor prescribed 5mg of generic zopiclone.  I get the metallic taste shortly after taking it but I've learned to keep a small glass of OJ beside the bed. This medication has been my saving grace! I almost get excited when the metallic taste comes now because I know I'll be sleeping shortly thereafter! If you've suffered from insomnia like I have, a little metallic taste in your mouth is a SMALL PRICE TO PAY!  I highly recommend zopiclone for insomnia!"
