Having been on the Atkins diet for several months now, I can relate to your dilema. It is difficult to limit one's carb intake even at home. On a cruise ship, it is even more difficult, but not impossible. Since I usually eat at the buffet for breakfast and lunch, I focus on omelettes, smoked salmon, deli meats and cheeses, as well as the salad bar offerings. At dinner in the main dining room, simply avoid the pasta dishes and high carb veggies. The waiter will usually substitute something like broccoli for potatoes if he is asked. There is a sugar free desert offering each evening, however; there are a lot of carbs in any desert, sugar free or not. As for the frozen thingees, most are made with fruit juices which I'm sure you know are loaded with fructose, a source of lots of carbohydrates. If you are happy with drinks like martinis, whiskey (or scotch) and soda, or perhaps something mixed with diet soda, you can avoid the carbs. Also, white wines, such as champagne, are very low in carbohydrates. Good luck, and have a wonderful cruise!
