I would advise you not to take it. My girlfriend took it and she changed within a few days of having it, and after taking it for almost a month, she was unable to sleep, really terribly moody, and just horrible to be with. She did lose weight, and her mind! She would be up at two am scrubbing the shower tiles with a toothbrush. She couldn't think straight because she had so many thoughts going through her head, she had heart palpatations, dry mouth, upset tummy....It was really horrible.
