Roger you are a smart guy so I'm guessing you already know this.... if you have a tolerance as high as you describe and you want to experiment with cutting out empty alcohol calories you might want to get a medical consult for detox.
You can always start drinking again if you want to after you find out if you can stop... You seem like the kind of guy that would want to know.
Calorie count - Alcoholic beverages
Alcoholic drinks, like many other drinks, contain calories that can add up quickly. Going out for a couple of drinks can add 500 calories, or more, to your daily intake. Most alcoholic drinks have little to no nutritional value. If you are trying to lose weight or maintain a healthy weight, you will want to watch how much you drink. Cocktails mixed with soda, juice, cream, or ice cream can have especially high calorie counts. If you find you are having trouble cutting back on alcohol, talk with your health care provider.
Here is a list of some popular alcoholic beverages, their serving sizes, and the number of calories in each.
