I'd wait for the autopsy report. Seriously, most fairly healthy people dont' die from a sleepign pill overdose, alone. They'll have to find out a lot before concluding that. Did he have alcohol or some other non-sleeping-pill drug in his system that reacted with the pills? Did he have an undiagnosed medical condition (like in the heart, which as we know takes a lot of people far too early in life).
But if it did turn out to be losing track of your sleeping pills, and that alone which killed him: wow, how I hope his family eventually can get past the pain and use this horrible tragedy to educate others.
Sometimes when a situation is shitty, but was preventable, that kind of thing can do a lot of good. Especially for kids and younger adults, who might not honestly take prescribed dosages very seriously. A lot of us don't always do this, including myself. But it is fucking DANGEROUS, even when it seems innocent. Especially with medicine you are inclined to forget that you took. Double-especially if you are like a friend of mine who absolutely insisted she always had to have at least double the prescribed dose, for anything to work. She was disabled, and at the time very ill with difficulty breathing.
Well, she's dead now, because her caretakers both gave her that double-dose while she was in reality suffering from pneumonia. Not overdosing might have led her to the hospital, which is the one place her life could have been saved.
So forgive me if I'm fucking pissed at this, though I never saw the young man's work we are discussing here. But people just need to learn (before it becomes a life-taking habit) that drugs aren't to be fucked with. I'm learning a lot on a personal level about what not to fuck with in the extreme, especially long-term. And more and more it makes my head spin what we consider legal versus illegal.
So, I guess I'm saying to honor the man. No matter what happened, let people know about it, especially younger people who may not yet be established in their life-shortening habits. You don't have to be a gossip-magazine regular cover to die from an overdose.
