Drank 11 hours ago, took antabuse (disulfiram) this morning?

Depends. The package insert says that alcohol can cause an Antabuse (disulfiram) reaction within 24 hours of drinking alcohol. However, in most cases, all detectable alcohol in blood and the body are gone within 8--10 hours, unless drinking has been very heavy and there is liver damage. If the drug is not deterring you from drinking, you should talk with your doctor about another anti-craving medication.
