I have suffered my whole life with sinus and asthma conditions and it always took 3-5 Antibiotics to take care of the problem that many times went to pneumonia. Then I learned about glyconutrients. I am now drug free and asthma free and if ever I get a problem that is now very rare but should I need an antibiotic, my body response immediately and starts to repair and recover within days. You can learn more by going to http://www.healthsugars.com It's changed my health for the better and I almost died in 1995 from this problem that never would get better. I have already had 4 surgeries on my sinuses. Yuck!!!!! I'm done with that.
