Para, you can do this. We all have that auto pilot in us. I know I do as well. You also have enough willpower to break this cycle. Use all of the resources you have to help you through. Reach out here as soon as you feel your auto pilot coming into play. We can't help you through your weak points unless you give us a shot.
You're not alone in this, but you've got to commit to yourself. Next time you feel yourself getting weak, have a plan in place of what you will do so that you avoid drinking.
