Turn the amulet of restful sleep into an amulet of sleep resistance, except it grants restful sleep (and no sleep resistance) instead while it’s cursed, and it still mostly generates cursed.

When you are wearing the amulet of restful sleep, you are given sleep resistance whenever the amulet is not causing you to sleep; this is because you shouldn’t be tired in between frequent naps.

The amulet of restful sleep confers hungerless regeneration whenever the player is asleep.

Rename the amulet of restful sleep to the amulet of narcolepsy.
