I know this will sound dumb. I've had several false starts. Maybe its psychological but if I could get past a full 24 hours then the voices in my head would begin to quiet. So when I knew I was going to attempt a quit I would drink twice as much as normal the two days prior. Pass out drunk. After those two days on Day 1, I was soooo hungover and sick they craving was not even there. That usually lasted another couple of days. Once I had 2 or 3 days under my belt I felt stronger and could go weeks and months.
Relapsing....now that's another story. But that's how I got thru Day 1. DOH!
