I get such bad upper respiratory infections and with that I also always find myself with a really nasty sinus infection. Whenever this happens my nose goes completely crazy and starts making a ton of mucus and making it really hard for me to be able to breath which makes it impossible for me to get any sleep at night. This is a really great nasal spray that helps so that you can get rid of all of that mucus from your sinuses. It is easy to use and you just spray it in and you can feel it start to loosen up all the mucus really fast. I always have to blow my nose right after I put this in and then I am able to breath so much better. The medicine continues to work for quite a few hours and keeps your nose running so that all of the mucus and congestion comes out. I do warn you though with this loosening everything up you are going to start coughing and it will also come out with that, it is pretty gross but it does a really good job to open up your chest and nose so that you can be more comfortable and feel better.
