I have had a chronic cough and clear mucus buildup for approximately 14 months. For 4 days this summer I went to Moses Lake (very desert-like) and except for when I was in air conditioning I had virtually no symptoms.For how long should I try your Sinus Rinse (and how many times a day) to properly determine if it will work for me? Thank you.
