I have a surprising number of friends tell me they have gone to some sort of drug and alcohol rehabilitation center. It's not limited to people from broken homes or junkies who hit bottom and have no other choice. These people are from good homes and are gainfully employed. They just have a problem controlling themselves around alcohol or drugs.
One friend told me that she wanted to leave about a week after she arrived. She was suffering from alcohol withdrawal, and the staff kept pushing her to attend early morning group sessions and do some demeaning chores. The center did say there was an "open door" policy, meaning anyone who wanted to leave voluntarily was free to do so. It was not a prison. In fact, it was one of the most beautiful facilities in the area.
She said that the grounds were so nice and peaceful that she spent a lot of time outdoors, which was something she rarely did when she was an active alcoholic. She said there were a few clients who tried to smuggle in contraband, but most of them were trying to get their lives back together and took the program very seriously.
