If you're interested in CAD why don't you go to the CAD/CALP forum and read back about three pages worth. It will answer a lot of questions you might have. There's also a cheat sheet and a stall list that you can print out and post where needed and carry with you. The cheat sheet has the rules and foods of the program and the stall list has things that can cause problems.

If CAD is for you, and you adhere to it strictly, will be the easiest program you've ever been on. And you get to eat whatever you want, in proportion, once a day. In addition, with your insulin under control, you'll feel how a "normal" person does about food and stop obsessing.

Good luck!!!
