You will master controlling your urge to drink. You will get your off button back. 
You will trust yourself again to not over drink.
You will be able to handle social situations and not cave in to the little voice in your head that says, "Just 1 drink won't hurt".
You will trust yourself to not end the day with a alcohol and you'll find authentic well-being when you don't over drink. 
You will manage your mind and make decisions ahead of time and stick with them. Ultimately gaining back self-control and self-confidence.
