Badberry

Up to ten berries appear in your hand and are infused with magic for the duration. A creature can use its action to eat one berry. Eating a berry restores 1 hit point, and the berry provides enough nourishment to sustain a creature for one day. The creature must make a Constitution saving throw upon eating. On a fail, the creature becomes drowsy, after an hour the creature falls asleep for 1d4+1 hours. 

The berries lose their potency if they have not been consumed within 24 hours of the casting of this spell.
