History: A 72-year-old hospitalized male died

following an intentional overdose of 90 milligrams of

zopiclone. The patient was being treated for lung cancer

I can tell u that during my drug abuse days I once did 58 7.5 mg pills so 435mg and blackedout. I woke up after I'm not sure how many hours of "sleep" and found i could barely think and standing up was impossible. I'm 21 and 186lbs so it all depends. Worst part about it after the first 8 pills i didnt even realize i was hurting myself or think of the possibilites. Zopiclonse really impairs u i just kept taking more and more
