re: Who drinks a lot of alcohol?

If you're drinking for a reason that you can't identify other than, "you like it," you have a problem. But it usually isn't the booze, it's what causes you to want the booze. (insert female emoji here)

I notice you didn't mention the wife/girlfriend at all, or your family, which are the most likely sources for you wanting escape. If you don't want to be in a relationship, get the F out. Don't drink to cover it up, especially if you're not already married.

Different people can handle different levels of consumption. Wait until you get old enough to learn that the 40 year old women are taking their kids to the mall with a 30oz cup full of wine, and you won't seem as crazy as you think you are.
