Zopiclone works really well, and the only side effect is a metallic taste in the mouth. I have insomnia too, but what happens to me is I fall asleep OK, but then I wake up ay 3, and can't fall asleep again until 5. I would take zopiclone, but my work does random drug screens and it is on the not allowed list because I think it tests positive as a benzo. I'd be on a different combo of meds if my pdoc could prescribe what she wants to. I have to take seroquel for sleep, and it doesn't work very well.
