I did my first Master-Cleanse back in Sept. Went for 17 days. It was a tremendous experience.
I experienced a very bad flu/cold throughout the clease. I kept telling people it was due to the cleanse but noone would beleive me. And a bad cough as well. Now, the reason I say this is because I have had a chronic cough off and on for years, often clearing my throat. Loved ones have told me that I have had a cough for 10 years.
I finished my second cleanse (about 11 days), last week.
I almost can't remember the last time I coughed. During the first cleanse I coughed up tons and tons of mucous, for days on end. Shortly after the first Master-Cleanse cleanse it vanished.
Somehow, someway, I believe that the first cleanse addressed the cause of all these coughs and colds in a way that no doctor could. (I have always avoided them anyway).
I believe the cleanse goes real deep to symptons or conditions we don't understand.
