I know for a fact that my mother, who lives alone, is abusing prescription drugs. She won't let my brother, who lives nearby, or me, who lives out of state, talk with her doctors. She takes Oxycontin and drinks while on it. Also she took Ambien a couple years ago and totaled her car (and fractured her arm in the accident) while sleep walking on that. We finally got her to stop taking that and yesterday she just admitted she is still taking it. What can we do? She doesn't think any of it is a problem.
