This worked for me!
I recently felt like I had a chest cold — lots of drainage, chest congestion, cough and some fatigue. I was taking vitamins and using cough syrup as I waited for this to arrive. I started it on a Thursday evening and by Sunday, I felt much better. By Monday or Tuesday, the cough and all chest congestion was gone. A normal Zpac works well for me, but will upset my stomach on about day 4. This did as well, which tells me it’s just as effective as a prescription zpac, AND all my symptoms cleared up with it. Due to the upset stomach, I stopped taking it on day 4. Then my son started feeling bad – headache, sore throat and started getting congested. I gave him the remainder of my pack and after two doses, he also felt better. He only missed one day of work, and I think it’s because he started taking this as soon as he started feeling bad. I’ve been telling everyone about it!
