Hey Andy, welcome, and best wishes in the journey you're beginning today.
It sounds like you might want to at least consult a doctor. Withdrawal can be dangerous. As MovingForward said, you might want to at least give AA a chance. I mean, this is your life at stake, after all. Can't hurt to check out a meeting or two.
You're lucky to have a supportive partner in this. Mine was not too sympathetic which made a tough situation a bit tougher.
Sobriety is awesome! Welcome to the club! Hang in there and keep us posted.
