I'm wondering the same thing myself! When I had my one-hour dietary session I asked about the 2-week window, and she (Kris) said it was just one week. I can't imagine there would be that much difference between doctors in the same clinic. Who did you get the two-week info from? I hope you only have to do the one-week also. I thought it would be easy; now I'm not so sure. Will have to be EXTREMELY focused on the goal! |
