hi Jf1,
don't know about over there but here we have Dr's who have specialised in addiction and work in normal private practice clinics
maybe a Dr like this would be more helpful in treating your back pain and is more aware of possible liver issues.
sorry to hear the alternative approaches have not been successful.
I also use discretion with who l tell l'm an alcoholic.
(mostly because it entails answering too many nosy questions)
The first step towards change is acceptance.
Once you accept yourself, you open the door to change.
Change is not something you do, it's something you allow.
