don't do it!!! my sister took them, now she's in and out of the hospital as they stripped her body of something-can't remember the exact word- and she's since lost feeling in her feet and her eyes were also affected, stay away from fad diets and pills, they usually get put on the market without much scientific research done and can do more harm than good!! i'd stick to a healthy diet and regular exercise.... the hospital told her it was the pills and she's now in legal action against them.
