Have you told yourself ? that you're done?
It might seem like a semantic difference only, but telling everyone that you are done in hopes that that will keep you 'done' , isn't what will get you 'there'.
You could make a permanent , unconditional commitment to abstain, you can decide to quit.
"I will never drink again, and I will never change my mind" is/was the only plan that worked for me. It's a Big Plan from AVRT, great threads on those ideas here on SR in the Secular Recovery forum and subforums.
Making a Big Plan and using AVRT to live comfortably with residual desire will definitely get you there.
I told my wife loads of times I was done getting plastered, telling her didn't help. Deciding to quit , telling myself I was done was the ticket.
" Do or do not, there is no try" wisest thing a muppet ever said.
You can Do it, rootin for ya
