Well I'm going to try it! I will order some today.
I had the flu a couple weeks ago but now that it's gone I have my usual lingering and annoying sinus blockage (mostly on my left side) In the past I would be jerked around by Doctors and still end up with blocked sinuses, sinusitis and sinus infections for months on end.
If Sinusbuster really works, I'm looking forward to the burn!
