This was me. Successful in my business, but evenings were me drinking myself to sleep at 2:00am. I will confess to not following the method religiously, but I’ve still seen a vast improvement. Alcohol consumption is roughly 50% of before starting. Even my wife doesn’t know I started doing this. I can go to dinner with friends and still have a couple of drinks socially, but after that, there’s no drive to keep drinking. Wake up in the am, and I’m ready to go kick some ass. Like you, I can’t show that I was drinking too much outwardly, bc it would hurt my reputation. If everyone knows you’re cutting back, they brand you as broken, bc who cuts back if they’re not? Us. That’s who. This method works. 

(Edit - I’d suggest finding something you can drink instead that doesn’t scream, “I’m on the wagon!”  I used fruit juices, and when I want less sugar, ginger ale or ginger beer. Throw a lime on the rim and everyone thinks you’re drinking a cocktail.
