Im usually a skeptic when it comes to natural things but I ordered the fizzies to support a small business and boy am I in love. I dont have issues with sinus but wanted to find something relaxing during my shower and this helped open up my nose, I felt refreshed, I kinda wish I was sick so I felt the openness but DAMN its so good. Please buy it and try it, I dont ever do reviews or anything but here I am telling you to just spent the 6$ and love yourself.
