Best thing ever! It totaly works! Started getting a cold/sinus infection Thursday....nasal congestion, cough, sneezing, drained, no energy...ya know, the typical cold/sinus infections symptoms. I started this and did it three times a day instead of calling my doctor for a Z-pak like I usualy do. It kept the edge off of it and kept it from comletely taking over and making me as sick. Today I'm almost back to 100%. I'm telling you it works!
