Nope. Not worth the risks and side effects that come along with it.
Diet aids such as Releana are not the best way to lose weight. While you might lose a considerable amount of weight on it, which might be nice, the chances of gaining it all back, once you go off the med are extremely high. I can't think of anyone I've ever known, who would stick to such a "diet" for any length of time.
You would be much better off with lifestyle changes, implementing a healthy diet and moderate exercise, making sure it's something you can stick with over the long haul.
