You are still early in sobriety. I can tell you absolutely at just over a year for me I feel like I have a competitive edge over other sales reps I work with because I am more energetic, more fit, sharper etc... At first, not so much, kind of like a turtle.
I am successful but I was resting on those laurels as I escalated my drinking, slowly heading down. I am not resting now. The person that got me to the top is back and climbing back up not sliding down.
You can believe whatever you want, but your best is not heavy drinking. No one is their best heavy drinking or drugging unless your best is followed by immediate death.
I am playing a long game, how about you?
