I mean you're not wrong, do people not know how these drugs work? They're not magic, they make you never want to eat and take away the "feeling like shit" when you don't.
That's not the experience my wife has had. She's been on one of these drugs for a while and still gets insanely hungry, but she's able to feel "full" with a much smaller meal than before taking the drug. If she overeats, she feels like shit.
