I always worked a lot of hours at a demanding job. My "reward" after dinner was a couple of beers to wind down before I went to bed. On the weekends I would drink more because I had the day off.
That pattern lasted for over 20 years, and yes my alcohol consumption increased both after work and on the weekend. And being a daily drinker for many years eventually caught up with me.
When I finally quit drinking, one thing I really tried to accomplish was to obtain balance in my life. I don't know your situation, but working 12+ hours a day is no way to have a quality life.
