I saw that episode. For some reason it was the most difficult one for me to watch. I think it was because of the kids. I couldn't believe she was drinking mouthwash, that was so gross.
I agree with you goodperson. Even if the addicts aren't ready for the intervention it's good for the family/friends to finally draw a line in the sand and get all that off their chest. For those who actually stick to their guns, it makes their lives a little easier not having to babysit an addict.
