Hi, Denial is common in people with alcohol related problems and it is often difficult to make them acknowledge that there is a problem. You mention having tried librium, but please remember librium is of benefit only when one has quit alcohol and is having withdrawal symptoms, which librium improves. It has no role in a person actively drinking. Disulfiram works differently. When people on disulfiram take alcohol, they are likely to suffer from reactions like nausea, vomiting, flushing, raised heart beat etc, and in some cases, reaction may be severe enough to need hospitalization and intensive care. That is why, disulfiram should not be given surreptitiously. There are other medications which do not have the risk of such adverse effects, but they are not available over the counter. Since your husband is unwilling to listen to you regarding this, try involving other members of the family/friends whom he respects. It is possible he may listen to them and agree to consult a doctor. Hope to have been of some help. Best wishes.
