AA is a great thing but every chapter is run by patients, not professionals and mileage may vary on sponsors.
There is also a skepticism regarding rehab.
The director of a top rehab clinic said something very sensible I thought: AA is great support but it is not treatment, after treatment is the time for AA.
Fortunately my wife is open to anything that will or might help and SW liked the idea of some real education and medical input to her recovery so we are finding a rehab counselor to work with 1:1.
I'm a former AA sceptic who is now a huge fan but not all groups are equal nor are all sponsors.
