I suspect you are going to have significant sleep problems with stopping alcohol. This is tricky. Taking a benzodiazepine (valium and similar drugs) is substituting one addiction for another and not likely to be a safer addiction! Melatonin if it worked, is not an addictive drug. Certainly meetings, some drugs (naltrexone and/or campral) can be helpful. You might consider CLONIDINE if there are shakes, sweats, heart racing with not taking alcohol. Clonidine is a stress hormone inhibiting blood pressure medication often used in addiction. It lowrs stress symptoms and also often makes people sleepy.
