Wakefulness (Reversible)

With this spell, the recipient is able to post pone sleep. For the duration of the spell, the creature feels wide awake and energetic, but immediately becomes exhausted when the spell effects wear off. A creature cannot naturally doze off while under the influence of this spell. When the spell does wear off, the creature suffers a -2 penalty to its attack rolls and saving throws until it has slept for eight hours. A spellcaster who has not fully rested cannot recover spells cast. Multiple wakefulness spells extend both the time awake and the sleeping time required afterward.

The wakefulness spell can be cast to counter the effect of a sleep spell on one creature. If a sleep spell is cast on a creature protected by this spell, a saving throw vs. spell with a +3 bonus is allowed to negate the effect.

The material component for this spell is a tiny glass bell.

The reverse, drowsiness, imposes a -2 penalty to the target creature's attack rolls and saving throws for 1 turn per level of the caster. Each full turn rested reduces the duration by two turns, shorter rest periods do not. A successful saving throw vs. spell negates the spell, and spells such as dispel magic can counter it.

The material component of the reversed spell is a pinch of sand.
