I can relate to what you are experiencing. I have had a sore throat ever since day three, and I am on day 11. Last night, I had a coughing fit that kept me up for hours that was only mildly productive. After which I felt I was breathing better than I ever had. I have been hoarse. Yesterday I decided to increase my cayenne intake and I believe it has helped to loosen some of the mucus that has been festering in my lungs for years. I thought perhaps I started this cleanse with a cold coming on as a lot of co-workers and clients are suffering with colds and such, but right now I am pretty sure this is all part of the cleanse. Even if I do have a "cold" this cleanse is probably better than ridding my body of it than anything else.
I am commited to continuing this cleanse until this clears up keeping in mind that what I am doing is a huge step toward helping my body become more healthy and efficient. This is the first time doing it and it's really helped me so far. It sounds like you are doing a great job and keep it up.
