Recommended WLS Reading

So my mental health consult appointment went well. I was cleared by him for surgery. So one more step down. Anyway he recommended I work my way through this workbook

I just bought it and expect it to come within the next few days. I am an emotional eater apparently and this is supposed to help with that.

Of course it's not like I have time for any more "school" type work to do, this Ethics and Patho class are already killing me. But I digress... point of this post, ANYONE ELSE HEARD OF THIS BOOK?
