Self Discipline And Pills

I just got back from post office, i sent some weight loss diet pills for my sister back home. She liked the kind that i brought to her when i went there for a vacation. She is starting to get conscious in her weight. She used to be skinny like i am, but now she gotten so big and she cannot control herself eating. So i suggested it to her that she needs pills for her problem and she's got to have discipline in her eating habit as well. It just doesn't work if she takes pills and she eats like there is no tomorrow anymore. She said that she lost some pounds recently which is good, it only tells me that she is indeed losing some weight and trying to get back to her original figure.
