A 32-year-old woman is scheduled for elective laparoscopic cholecystectomy under general anesthesia. She reports having a light breakfast (toast and jam) at 06:00 AM. The surgery is scheduled for 12:00 noon. On pre-anesthetic evaluation, she is anxious and asks if she needs to fast further or if she can have some water now. Her vital signs are stable, BMI 24 kg/m², and she has no comorbidities. What is the most appropriate fasting instruction for this patient?
