Yes. I have had to work with my GP who's prescribed Zolpidem ER, which is not as good as the name brand, Ambien. Insurance won't cover the cost. I've added an over the counter melatonin chewable tablet to the Zolpidem and that has worked great. Fast REM sleep, but I get only a maximum 6 hours and then I wake up, eat breakfast and go back to sleep for a couple hours. I really want off of the prescription med.
