I lost a brother to addiction. I know that a lot of people never hit rock bottom no matter how bad it gets and they can't turn it around. A lot do and I do hope that the celebs eventually do get it turned around.However I know that they are Attention Whores enough to be willing to be on TV during a very bad time in their lives. I think sometimes they do know what will give them camera time and unfortunately that isn't always what is best for them on the road back to sobriety.
I do hope these shows help people see that it is an ongoing struggle and not something that should get fixed with a few days in rehab. Unfortunately having a few relapses is usually part of the process. It is what you do when you relapse that makes all the difference.
So while I do want to see them all get better, I know they are willing to be train wrecks just to get the screen time and so I expect they will give us plenty of bashable moments because that is what keeps them off the cutting room floor.
