I think I may be in the minority, because I tapered down over the course of several days. I knew I desperately needed to quit, but the actual day felt random but firm. Thoughts of drinking popped up, but I kept saying "no" (yeah, out loud when needed), read here constantly, had a plan in place for what I would do when I wanted to drink (journal, read, lay on a heating pad, etc.) I just had to make a decision and not drink no matter what.
