No Bed for Two Years

In his younger years, Rav Eliezer sat and studied together with his older brother, the Imrei Chaim of Vizhnitz, and their exertion in Torah study was legendary. For two years, the brothers were so engrossed in their studies that they didn’t sleep in a bed. Except for Shabbos, they didn’t even change their clothes from week to week. When they needed a short rest from learning, they simply lay their heads down where they were, while fully dressed – and thus they could use the entire night for Toras Hashem!
