sinusitis
"Fantastic at clearing the sinus infection. I'm on day 4 and it's almost completely gone. The first two days were miraculous. 



But then. Starting day 3 ...



My stomach and intestines are rumbling almost constantly and I'm "pooping" brown water 5+ times a day. 



I'm also utterly exhausted and weak, making it virtually impossible to actually do anything. 



If this gets much worse, I'm going to have to stop using this before the 10-day course runs out."
