British Liver Trust - more advice about liver disease, home of the main UK liver disease charity and liver disease support groups
Alcohol Concern - general advice about alcohol problems, and sources of help
Down your drink - specific advice about alcohol dependency and alcoholism, and a web based treatment program for alcohol dependency
Alcoholics Anonymous - AA are there to help people with alcohol dependency and for some people they can be enormously helpful. As AA is essentially a self help organisation different groups can have a very different feel, for example some may be quite religious, some not at all. If you do have a dependency problem then you should definately check out AA, and if one group doesn't suit then try a few more before you give up on them.
