In this article the doctor talks about how a person would never get prescribed all these meds at the same time. Even if he ways, for me common sense would prevail and I would know not to take "two prescription painkillers (oxycodone and hydrocodone); two prescribed anti-anxiety drugs (diazepam and alprazolam); and two sleep aids" at the SAME TIME.
