An alcoholic is someone that can not self regulate and does not know when to quit. I would suggest based on the people I have known that you are not but that you easily could become one. My advice is to trade beer for something else when you drink for a while and see what happens.
Consider this at this time you have a good deal of free time. Imagine if your wife tells you where to go and leaves you then you will have more time. My suggestion to see if you can find something that you both like and do it. I have started going window shopping only because she likes it.
You re in more danger of screwing up your life with your family than you are at this point being an alcoholic but if you screw up the family you could end up there easily.
