You wrote that the med is a "controlled substance." There may be side effects or withdrawal at play here. Also, just the fear of running out or being unable to get the prescription filled can cause one's temper to flare. What if it snows? What if the cars break down? What if everyone gets sick and can't go out in four days?

I certainly don't condone the behavior. But I can say that these types of meds have spiked my wife's worse behaviors, not to mention the pain the meds are meant to treat.
