The Sleep spell is useless in combat when enemies are able to shove each other to wake each other as a bonus action. The spell description in the core rules specifically states that waking a creature from this spell takes an action. In BG3 it is easy for enemies to attack on the same turn they would have otherwise already used their action, effectively giving the enemies two actions and wasting the player's spell slot.
