A glass of beer and a shot of booze have roughlly the same amount of calories in them. So substituting one for the other really isn't going to change anything unless you go to a light beer, then at least you have maybe half the caloric intake. But what will happen is if you pour yourself big drinks, and fill them full of juices, you will take in more calories, just from the sugar, and not moitoring how much wiskey, vodka, or whatever you pour, is going to increase after the first one.
I still drink, but try to keep is social, on wekends, not every night, and not alone, my buddy of 50 yrs almost died 3 years ago in an alcohol induced coma, it took 3 months to get him back, he was just bored and always a big drinker. We found him on the couch after 2 weeks of no contact, half dead. Emt's rushed him into the hospital where they really didn't want anything to do with him. I got him into a rehab and he started snaping out of it after a few monts, but almost died, He hasn't had a drink since. Now he just watches porn, lol.One beer a day isn't going to hurt anyone, or a glass of wine with dinner, it's actually good for you in moderation, but the problem is that some folks can't moderate anything. So if you have an eating problem, it's easier to assume you can substitute it for a drinking problem.
