Severe morning sneezing with watery discharge is commonly due to allergic rhinitis, often triggered by exposure to dust or bedding. Try to keep your bedroom clean, wash pillow covers regularly and avoid direct contact with dust. Steam inhalation and saline nasal rinsing can help clear the nose and reduce irritation. Since tablets like cetirizine are not giving lasting relief, your condition may need a different approach. Consult your doctor for proper evaluation and long-term management.

Continuous sneezing for a couple of hours is often due to strong allergy triggers such as dust, cold air, or exposure to odours. Try to stay away from triggers, keep your surroundings clean and use a mask if needed. Steam inhalation and keeping your nose moist can help reduce irritation. Rest in a warm environment and avoid sudden temperature changes. Consult your doctor if this keeps happening frequently to find the exact cause and proper care.

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.

Allergic sneezing is usually triggered by dust, cold air or other environmental factors. Try to avoid known triggers, keep your surroundings clean and use a mask in dusty areas. Simple measures like steam inhalation and staying hydrated can help reduce irritation. The choice of medicine depends on how severe and frequent your symptoms are. Consult your doctor to decide the most suitable treatment for you.

A frequent runny nose like this is often due to a persistent allergy or a condition like non-allergic rhinitis, so it may keep recurring with triggers. Long-term use of cetirizine is generally safe when taken as advised and does not usually harm the kidneys or liver. Try to identify and avoid triggers, maintain good nasal hygiene and keep your surroundings clean. As symptoms are long-standing, consult your doctor to review your condition and discuss more effective long-term options.

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.
