Where is the miracle weight loss drug?

in an age where many physical and mental diseases and disorders are either totally eradicated or easily treatable, why havent companies been able to make a weight loss pill that works more often then not? if u give people enough alcohol, they get drunk. enough epicac, they throw up. enough tranquilizer and they p out. so why not enough [something] and you loss weight? from a fiscal stadnpoint they have nothing to loose. we can still eat all the fatty foods we love. the pharma drugs will still be sold because weight only ads to certain illnesses, not causes them. they could charge ludacris amounts of money and by god they would make hundreds of billions more. and if we got fat again, just go out and buy more of the drug and viola, more billions. working out and eating right is great but so time consuming and tough. so my question is; is there any weight loss drug that has a proven track record? and please dont mention alli. i dont trust the fda as far as i can throw them.
