I have to use Otrivin mostly during the season changes and winter to keep breathing normally. I am aware of Otrivin addiction which i have experienced earlier but no other nasal spray (saline sprays) work for me and I am taking Otrivin one spray each nostril before bed. As expected, after few days, without any reason my nostrils remains blocked through out the day and became a pain for me to work. I remember, years back Dr. prescribed me Duonase for some reason which helped. Should I try Duonase, and how do I get rid of Otrivin addiction, and get a sound sleep keeping my nostrils open during the night without Otrivin? Thanks, Sandip Ray
