I have had a series of sinus infections every year for the past many
years.  I work in a school, and as you know, there are many germs
floating around in school settings.  I bought No Sinus Pain this past
fall, and at every sign of a head cold, I have used the inhaler.  It is
amazing! Between it and Emergen-C, I have not had a sinus infection
(knock on wood!)  yet this school year.  I plan to let all my friends
know about your inhaler products! Colette Babson
