Sneezing after staying in an AC room is often due to sensitivity to cold air or dryness. Try setting the temperature slightly higher and avoiding direct airflow on your face. Keep the room clean and ensure the AC filters are regularly cleaned to reduce exposure to dust. You can also use a humidifier or keep some moisture in the room to prevent dryness. If the problem continues, consult your doctor for further advice.

A dry cough with vomiting after food may be due to throat irritation, reflux or persistent coughing spells. Cetirizine may help only if an allergy is present, but it may not fully control these symptoms. Try taking small, frequent meals, avoid spicy or heavy food and keep yourself well hydrated. Warm fluids can help soothe the throat and reduce coughing. Consult your doctor, as this requires proper evaluation and appropriate treatment.

As symptoms are long-standing, consult your doctor to review your condition and discuss more effective long-term options.
