Alcohol can cause great and irreversible damage to human body. Liver is slowly being disintegrated, which can lead to cirrhosis and late esophageal varices and gastric bleeding. There are many other problems that are caused by alcohol, but I mentioned this particular one because most alcoholics die from bleeding to death. Abrupt withdrawal from alcohol can also be very dangerous and even deadly. So all in all, it is a very bad drug.
There is a new FDA approved treatment now and most insurances cover it. It is an injection called Vivitrol. I highly recommend that you and your mom look into it. It works for a full month and can be repeated as many times as needed. It will take away your mom's drive to drink as well as make her feel unwell and not drunk if she does choose to take a drink.
You can also encourage her to join a AA group to talk her issues out and do show her the video. Good luck.
I am not sure there is a question here for me. I feel very badly for you. Did you post this on a general Addiction forum? This is the "Expert forum". Do you have a specific question for me as a doctor? If you do please come back and ask me again. But I think a video is a great idea. I wish you and your mom the very best.
