Has anyone tried or knows someone who has tried the new "Ambien CR" I've seen advertised on TV? It is supposed to have a continuous release feature that not only helps you to fall asleep but reduces incidence of waking through the night. I have horrible trouble both falling asleep and staying asleep. At the moment I'm on Lunesta, but I am waking up every hour or so. I'd appreciate any advice or info.! Thanks!
