Reply #48: The Antabuse is to prevent him from drinking.

[Cleita]

If you drink while taking it all kinds of nasty unpleasant things happen to you. The theory is that the unpleasantness of the after effects will stop you from drinking, a sort of Pavlovian response.

I also know how clever drinkers are in getting drink even when family and friends try to keep them from it. So locking the liquor cabinets, and his inability to go to the liquor store wouldn't stop a determined alcoholic. I think he's not been drinking in the last week or so. He seems to string his thoughts together better, but it won't stop him from obtaining hooch when he's down.

There are all kinds of aids and SS guys he can bribe or blackmail to be his liquor dealer.
