A 42-year-old male with schizophrenia was started on haloperidol 10 mg daily 2 weeks ago. He presents with intense inner restlessness and an inability to sit still. He paces the hallway constantly, rocks back and forth while seated, and describes a compelling need to move that is 'like being tortured from the inside.' The restlessness is present throughout the day, affects his entire body, and is not relieved by movement. He reports no worsening of symptoms in the evening, no uncomfortable leg sensations when lying down, and no relief from moving his legs specifically.
