In the 15 days following the inclusion, participants will receive two successive phone calls. The first call will be performed by a physician investigator of the study who will: re-explain the principles of the study to patients, check the absence of non-inclusion criteria, and note the medical history, date of baclofen initiation and current dose, undergoing medications and current doses, occurrence of AEs since the initiation of baclofen, birthdate, weight, and height. The physician will also check whether specific safety elements important with regards to the baclofen treatment are noticeable in the patient: history of seizures, suicide, and other concurrent substance use. The second phone call is performed by a clinical research associate (CRA) who will check the absence of non-inclusion criteria, and collects the 30 last-days reported alcohol use according to alcohol timeline follow-back (A-TLFB) method, date of initiation and current dose of baclofen, severity alcohol dependence questionnaire (SADQ), alcohol use disorder identification test (AUDIT), and A-B neuropsychological assessment schedule (ABNAS) which scores the current level of sedation in patients with psychotropic drugs.
