Why does thenOrbera work for some and not others. I've spoken with people that have gotten the procedure and the entire month or two of having it all they do is have nausea and vomiting , so at that point they get tired and have it removed and they state they haven't lost a pound how is that possible. However, ever doctor I've heard speak on it claim the weight loss is mostly in the 1st and second month. Is this a fad?
