    Works but gives me stomach cramps

    Posted by ALoren on Sep 28, 2013

    This one improves my mood but causes some stomach cramps/bloating and nose block. I had to stop taking it.

    Thought it would help me sleep -- it seemed to keep me awake!

    I'm not sure

    Posted by Reviewer2993334 on Aug 14, 2010

    It did not seem to work for me. Maybe i should hae taken it a few more weeks. I think i'll give it a try one more time.
