Glad to hear you're ok FF,
Antabuse won't help you enjoy life without alcohol and it won't stop those ridiculous fantasies - in my experience only building a sober life you love can do those things.
Some go to AA or another meeting based method, some find things like Rational Recovery work, others see doctors, counsellors or go to rehab, some find religion...some folks have other mental/physical issues to deal....and some just work out where and who they want to be and set out on the journey.
as always wishing you well man
