I do not know what "obesity drug" means. I take diet pills that curbs my appetite. My problem is overeating. The pill also helps build energy from the fat. Usually bigger people are lethargic. I do not get this way except after a few days of not doing anything.
It worked and I lost 15 pounds in 2 weeks. It is a lot of weight to lose at first, but after the two weeks the weight loss got slower (which I hated). This made me quit, but I am going to start again. It is about being healthy and some people need that help.
