I have not been on the SBD, but I have the book and have adapted some of the concepts to my own weightloss plan.
Generally, the first few days of any diet is the hardest because your body is adjusting to it. If you can stick it out for a few days, you will probably find that a lot of your hunger/cravings go away.
There are lots of veggies you can eat on SBD. Not only are they healthy, but they contain fiber and bulk which will fill you up. Why not plan to have a big mixed veggie salad with olive oil & vinegar dressing when you get hungry?
Or maybe make your eggs & bacon into an omelet with some asparagus, mushrooms, and fat-free cheese?
Hang in there. It gets better
