@sueinmn I also do several things to safeguard my sinuses and breathing. I use two sprays of fluticasone nasal spray in each nostril, I take two Mucinex daily, and I do a nasal rinse every day at bedtime. I also take a cetirizine every night at bedtime. The combination of all those -- in addition to my twice daily breathing treatments -- has worked pretty well for me thus far.
