Sleep resistance is an intrinsic which prevents you from being put to sleep by wands of sleep, potions of sleeping, sleeping gas traps, and orange dragon's breath attack, or when wearing an amulet of restful sleep. When you acquire the sleep resistance intrinsic, you get the message "You feel wide awake!" It can be acquired by: * Playing a Monk or Elf of level 4 or higher * Eating a monster which confers the intrinsic (e.g. elves of all kinds, homunculi, gelatinous cubes) * Being polymorphed into a naturally sleep-resistant monster
