Mine was almost 2 weeks ago, and it was 10 minutes tops. I had just spent a full hour with the nutritionist. I was surprised that mine was just a series of quick questions. The ones that stood out for me were the big scary ones: have you ever binged and purged, anorexic, cut yourself, done harm to others....etc. These were mixed in with more mild questions. I was a bit nervous too, but it was all good.
