My brother Baruch, of blessed memory,23 told me in Homil over a couple of LeChaims that when he was studying in Tomchei Temimim in Lubavitch, the Rebbe Rashab instructed him in yechidus to stay up (and study, “zitzen”) seven nights. How? “For example: when you awaken on Thursday morning, you must not lie down that entire day; then stay awake the whole night and — for the entire next day — not lie down until the evening. ”
Each time he was apprehensive: perhaps he had dozed off? So he would do it again. In short, he stayed awake in such fashion for 15 nights.
