<p>Im sorry for your loss emberjed, but is there a reason why you think the overdose was intentional?
Some meds have a therapeutic dose that is close to an overdose, making it difficult to regulate treatment. Its possible that my father took an accidental overdose of his meds, rather than intentional, because people can be disorientated and not realize the level of the drug already in their system.
The pain meds I am taking for instance are notorious for accidental overdosing, so I am being careful but its also important not to let the pain get away from you because then it is even harder to control it again.
Illegal drugs are also hard to determine dose because not so many studies on the medication.</p>
