There is 50% improvement. Previously I used to avoid cold drinks, juices and ice creams as I used to immediately get blocked nose, runny nose and cold symptoms on having them. But now I can take cold drinks, juices and ice creams. Cold symptoms are less. 

I think my sinus problem has stopped spreading but still not completely cured. I often have the symptoms everyday intermittently, but the frequency of colds has reduced and the severity has come down considerably. The runny nose remains for sometime and then disappears.
