Before I started the Z-pack I stopped at Super Supplements to pick up some Vitamin D and on a whim I asked the clerk if they had anything for a sinus infection. She recommended this nasal spray called Xlear (Clear but with an X). It contains xylitol, which is good for sinus infections as well as for dental problems. I decided it was worth a try before condemning myself to 6 months of third world belly.
My sinus symptoms got better within about an hour of my first use of Xlear and by the next day (Thanksgiving) I was all better. I love this stuff!
