[Vipergrün]

Two things to mention. If you are constantly plugged up, have poor sense of taste and smell, get checked for nasal polyps. I had literally hundred removed and it was amazing to be able to breathe, smell, and taste again.

Also, if you use too much of the spray, it will eventually make things worse, and will stop working.

I only use OTC stuff now once in a while.
