Family members need to realize that they did not cause the addiction. They also need to allow professionals to help the addict. Alcoholism and Drug addiction is a brain based disease. If your family member was doing crazy things that seemed out of character and was causing chaos in your home, you would take them to the Doctor to find out what was wrong.
With addiction we tend to enable by covering it up, or not allowing the addict to suffer the consequences of the addiction related behaviors. Many times pain is the only thing that can get the addicts’ attention.
Great video on how Family Members can help an alchoholic through Al-Anon meetings. I hope you will take a moment to watch! http://www.youtube.com/watch?feature=player_embedded&v=1XGrH7XY9X4
