I have the same book! I really found the exercises useful at first. After a while they became a little overwhelming as far as the amount of time needed to complete all of them. I am still using some of them to remind myself of why I'm thinking of food when I'm not hungry.
Hope you find it useful too! And don't be embarrased to be looking for a solution to your problem. Your boyfriend should be sympathetic rather than scornful. Mine doesn't necessarily want to hear all of the information in the book but he admires that I'm losing weight. Tell your guy to get with the program!
