I found that the best way to get past sweets is to stay away from them completely. That includes any low carb sweet substitute. It broke my cravings a lot faster and I now have some control. I still occasionally have an intense desire for golden grahms without the milk, but I'm not sure why
The important thing is to learn control and good eating decisions. I've been doing this for almost 7 months and am still normally under 20 grams.
As for veggies, find ways to sneak them in. Make stir fry. Sautee them and "smother" your meat with cheese and the veggies. I've found the clam chowder recipe on the recipe thread is not only super yummy, but a good way of sneaking in lots of veggies. Just a few ideas.... Be creative! The good news is that it's very likely your tastes will change. Getting over that super-sweet addiction, food will start to taste different to you and you'll find that you savor the other stuff a lot more.
