In retrospect, this has worked out fantastically for me. I love Sundays now - there is a sense of peace most Sundays which is great. I enter Mondays feeling refreshed and ready to work. I would recommend taking a Sabbath day once a week to anyone, I think it is beneficial regardless of your beliefs.
Two notes: First, the idea of a Sabbath is not an idea that condemns work. Christian theology holds working well as a moral virtue and something that honors God. In fact, part of taking a Sabbath, I believe, is working harder and being less lazy the other six days of the week.
Second, Whether taking a Sabbath is mandated for Christians is a debated issue, though I personally think it is not. The difference between the ceremonial, civil, and moral law of Judaism and the law's applications to Christianity is a complex topic. Christians are definitely not held to the ceremonial/civil law, but the command to keep the Sabbath is part of the Ten Commandments, and thus some view it as a moral imperative. I feel that in the spirit of Christian liberty (a freedom of action but still subject to God's moral principles), taking a day for a Sabbath is a personal decision.
