Hi, In my book the main character's mother is an alcoholic. At the beginning of the book my main character is a teenage boy and his mother is already an alcoholic he and his family preform an intervention and she ends up going to rehab. She comes out of rehab clean and stays that way for a few months and then she begins drinking again. She drinks on and off until the point where her family leaves her. The main character is now an adult and his mother still drinks he chooses when he sees her. Now, my question is could this happen? Could she drink on and off for years? I am also looking to find out anything I can about Al Anon, rehab, interventions or anything anyone can tell me about alcoholism. I know this is a very sensitive subject so if you can help me at all please feel free to message me.
