Have you ever tried melatonin for sleep? Its a natural sleep aid you can buy over the counter. I had been having difficulty sleeping when I was taking lexapro at night, someone here suggested melatonin and it worked even better for me than ambien!I couldnt believe it. I did feel slightly hung over the next day if I didnt allow for enough sleep by taking it early, but even that wore off quickly. It might be worht a try.
