You might find that the sacrifices you make will not pay off in academic success, and that will feel even worse. By the way, you will feel miserable living in a dorm. And consider that if you go to that school in the college town, try to study at the libraries of one of the law schools in your home city. They should be able to make an arrangement. Why are you considering this school far away?
I plan to study hard-core from Sunday night - Friday afternoon, then do my best to be completely "at home" on weekends. With luck, 2L/3L years I'll be able to schedule myself so I can have an extra night or two at home each week.
