hi Karen,
There are a number of members here who are indeed having good success with CAD. You're less than 10 lbs from goal weight; good for you to recognize that lowcarbing needs to be a way of life for the rest of your life ...
... The Heller's "Healthy for Life" is based on their CAD program; perhaps your library might have a copy you can borrow. (Great recipes too)
Every person is different, but my thought is that if you are truly carb-addicted, then even the Reward Meal could pose a problem for triggering intense cravings, depending on one's food choices. Perhaps for most days, the carb-meal would consist of high fiber, complex carbs such as potatoes in their skins, pulses(legumes), whole meal bread, brown rice and the like ... maybe a fresh fruit-based dessert. And reserve the sweet goodies, and highly refined white flour treats, cakes etc for very infrequent occasions.
I have heard of some folks who choose to have the carb-meal at breakfast, rather than later in the day (insulin is known to be most sensitive after the night-long fast) ... this allows them to have whole grain breads, cereals, fruit etc to start the day, then choose lowcarb meats and vegetables for the rest of the day. The point is consistency though ... you must consume the carbs at the same time every day, within that one hour window.
Best of luck to you, and enjoy the holiday in Portugal. Wow, June isn't far off ..
