limited benefits

I was very glad when finally got a xylometazoline hydrochloride-free nasal spray on the market. The first feeling in the nose was good - the aerosol shot vigorously and intensively in the nose. But then happened longer anything, except that now the spray breathing even more difficult as extra fluid in your nose for at least 5 minutes. After that, the nose was again just as congested as before using the spray. About a quarter of an hour after use, you can make up with a lot of good will have minimal effect, but this is so marginal that it could be my imagination.
It takes a lot of good will in order here to be able to find limited use.
