This is a very said thing. People instantly think suicide, when I was going to school to be a drug and alcohol counselor I learned that alot of the time, (mainly older people) they take their dose then forget they have taken it and take it again, then from here it's like a snowball, until it's over.
Not saying that's what happened , just saying it does happen. Either way it's a sad thing to hear.
Take care
