I would recommend she see her doctor, and that she get involved in a comprehensive alcohol use disorder program
This would include
a. Assessment by her doctor.
b. Psychologist or pyschiatrist with alcoholism training.
c. 12 step group attendance.

I am a double board certified clinical doctor with over 20 years helping people with alcohol problems.
