I work about 65 hours a week, granted it isn't hard labor. I also walk to work, about a 15 minute walk usually in extreme heat. My wife and I have still managed to pray 3 Rosaries every day since our marriage. On Sundays, after prayers and vespers, I usually have a few beers and sometimes even whiskey. I might only help once or twice a week by cooking or cleaning the floor, but that's it. I never felt guilty about it at all.
