Being healthy gives you that time. Alcohol makes you tired the next day, then you come home and drink again because you feel like garbage so on and so forth. You also lose time to the extra sleep your body needs to filter the poison out.

I'm not about to say that it's easy. I've done a ton of after work drinking in my day. If you're able, going a week or two without a drink really helps to sharpen the difference when you go back. For me that's what put it all into perspective.
