Stop taking Antabuse if you are going to drink.
Better, stop drinking and take Antabuse in the correct way so that it can help you.
Best yet, do those two things, see your dr and be honest about what's going on, and start going to AA.
EVERYTHING else can wait, and I mean everything.
Do you want to quit?
Your answer will tell you what to do. Stop drinking and start getting healthy; keep drinking and messing around with a serious drug, stay in the drama of a bad relationship and its entrails, and stay stuck.
You get to decide.
Good luck.
