diverticulitis
"Some diarrhea, besides that no side effects whatsoever.  I had read some of the side effects and it bothered me when I started the medicine but nothing happened while I was taking it. I didn't get tired, did not hurt my stomach, nothing.  The added benefit was that I had a knee I injured about 6 months ago and it hurt almost constantly.  After taking the medicine a couple of days the pain in my knee disappeared. "
