So, please help me understand. From what I gather you have to have a bmi over a certain amount to qualify. But once you've qualified, what happens when your bmi goes under the qualifying level? If it's 30 and you get to 26 but goal is say 23 do they keep giving it to you until you get to 23? How is this different from someone who is currently not on the med but has a bmi of 26 wanting to get to 23? Just for the record, I'm not planning on taking it. I just want to understand how it works.
