Query: Didn't agree with me

I am a runner and every day exerciser. I liked the idea of the Zyflamend and when it was offered to me through the Vine program I jumped to get it. Well, I have been taking it for just about a week now, and I can tell you that I have not derived any benefit from this with the exception of some really bad stomach and intestinal troubles. I am not sure what is causing it. From looking at the ingredients, it looks like a lot of the stuff I already have in my spice cabinet (oregano?), but there is something in here which does not agree with my digestive system. So, after a week of taking it, I am done. Thought I would develop a tolerance, but it never happened no matter what I did (eating or not eating before or after taking it didn't make a difference either). Maybe it's just me, so I am rating it a two star instead of a one star.
