Hi Jane, good to see you back.
Sorry to hear of your slip, but I think we'll all been there. The important thing is to get back and keep trying.
There are other meds to help you, naltrexone and campral come to mind. Perhaps your doctor has seen good results with these.
Nevabetta, antabuse I think can be compared to a "crutch" which is a tool to use until healing happens. It's important, at least for me, to use the time I'm on it to change my behaviour so that I can make better choices for myself in the future.
Keep well
Ron
