Insomnia
"Eszopiclone by Teva was an awful sleep medication for me - 4 nights of almost no sleep accompanied by a dreadful metallic taste that stays around for 12 hours. As good a sleep aid as Quetiapine was, this drug was dreadful. I&#039;d stay far away from this drug. Perhaps the brand name drug Lunesta is better, but my insurance didn&#039;t cover it."
