Thanks for the responses! I will definitely have to think about it - there are two Bariatric centers in my area (Ann Arbor, MI), The University of Michigan and a Barix Clinic in Ypsilanti. The U requires the six months in the last two years regardless of what insurance requires. I don't know much about the Barix clinic, but I will post something to see if anyone has gone there. I am still leaning towards a week or two of weight gain or slamming a gallon of water before weighing in.
