Wikipedia’s alcoholism page now contains a reference to baclofen:
Baclofen is an agonist for the GABAB receptors which suppresses the motivation to consume cocaine, heroin, alcohol, nicotine and d-amphetamine by inhibiting both withdraw symptoms and cravings. The use of baclofen for the treatment of alcoholism came to widespread public attention as a result of the publication of The End of My Addiction by Dr. Olivier Amesen in 2008, later re-released as Heal Thyself. Currently, clinical trials of baclofen are underway in several countries in Europe and the United States with a view to having baclofen licenced for the treatment of alcoholism.
This perhaps reflects that the drug is starting to be accepted simply because of the widespread successful use by a large number of people, as well as the press coverage it has received and studies underway.
