Psychological Evaluation info?

I first had to do a lengthy questionnaire on myself, eating habits, bingeing, stress and personality type questions.

I then had 1 hr appointment with my bariatric psychologist.
Can't remember her questions now, but it was mainly re my life, support, expectations, and my recently diagnosed thyroid disease.

It all went well, and I had to see her again, just before my op, and then every month post op, for 6-7 months.

Everyone's doc is different, and mine was two years ago... but mine just asked questions about
why I wanted the surgery,
what my expectations were after the surgery,
any medication I was on,
I think they asked if I had any depression or anxiety...
I remember thinking it was much easier that I thought it was going to be.

Hi guys, 

I just booked my appointment for my psychologist appointment. He said that the appointment would take around 2 hrs (!!) and explained a little about what was involved. 

Can anyone give any info on what to expect?
