A few things. First, I think it helps to realize that this really is as much a physiological problem as an emotional one -- if you can just find the strategies to get you through withdrawal -- yes, you may go through withdrawal -- and get past the physical cravings, it will get easier.
Here are some strategies:
* Keep your blood sugar stable! When your blood sugar drops, you will crave sugar or other fast acting carbs that will just keep you on the roller coaster. Eat a minimum of 14 grams of protein for breakfast every day, and no high impact carbs -- no toast, no muffins, no bagels, nuthin'. If you like, you might have a serving of low sugar fruit -- a few strawberries, some raspberries, a wedge of cantaloupe or honeydew, perhaps even a half a grapefruit. Not juice!! Breakfast is essential to your strategy, since it is a major determining factor in your blood sugar level for the rest of the day. Since you'll likely find your appetite far less than you're used to, you might eat a bit before you get hungry for the first few weeks, as your body adjusts to your new way of eating. Otherwise you may find your blood sugar has dropped and you're craving again. Have a handful of nuts, a piece of cheese -- something quick, easy, and portable -- with you at work. Pretty soon your body will adjust, and become more efficient at creating what little glucose you really need from protein and, to a much lesser degree, from fats, and you won't have to worry about it.
