"Lunesta vs generic 
I have taken Lunesta for several years.  My mind refuses to turn off at night and I typically would only sleep three hours or so. Lunesta worked great!  I fell asleep fairly soon after I took it then woke up at 6am without drowsiness.
This generic however, does absolutely nothing!
My mind races all night  long.  I spoke with pharmacist about this being a placebo.  He said that all generic companies are reputable.
Insurance will not cover Lunesta without a reason.  Fortunately, now I have one.  This drug (RDY eszopiclone)  should be analysed by the FDA."
