LOL. Believe it or not, that sounds like a normal psych eval. (Yes, I've had more than one). Many people who were addicted to drugs and/or alcohol, transfer their addiction to food. So when you take away the food, they go back to alcohol and drugs or shopping, sex, exercise, even eating disorders. It can get crazy. He was just trying to determine if that was a risk for you and something you need to watch out for. In addition, study after study has shown that a large percentage of WLS patients have been abused, especially sexually, men and women. They don't talk about it, they don't think about it, they eat. Again, you take away the food, you take away the coping mechanism. That's a problem. Studies have shown that people that have been sexually abused lose significantly less weight with WLS than people who haven't been abused. It shouldn't disqualify you but it's something he should point out to you so you can be aware of it and address it if you see it popping up in your life.
If you're open, you're honest, and you're willing to address any issues that may pop up, you're going to be fine.
