This crap does not work. They are combining two drugs one of which is a migraine drug. There are serious side effects to taking this stuff. It is not intended for long term use and one of the drugs has been linked to birth defects (surprised?). There is only one way to permanent weight loss. That is eating the correct foods. You can not keep eating what you are eating if you are fat and think that one day you will lose the weight by just eating less of the shit you put in your body.
