Not only it wouldn't work if you were to give it to him w/o its knowledge but he'd puke his guts out after he's had his first morning one. There's only one known substance which acts as a crave killer methadone style and gives alcoholics the time to review wtf alcohol lead them to. It's sodium oxybate aka- regretably - the infamous GHB. It's called Alcover in Europe and it's a right on label use, Xyrem in the US but that's right off label. Talking to a serious alcohologist - provided he wants to take actions - you may want to talk about it, as well as a possibly try with Phenibut. But a GP wouldn't even know what you're talking about
