Hi Jen -
I've been following atkins since mid-July and am currently down 41 pounds.
Here's my advice.
1. Change your focus! This is much easier when you're enjoying and appreciating all the great things you can eat instead of dwelling on what you can't. Gathering up a good supply of low-carb recipies to try will help with this.
2. Read labels. Always. Even if it's something you don't plan on getting or eating. It keeps you aware of what you're eating and when you find yourself in a restaraunt or other situation where you don't have a label, you'll know enough to make a good estimate of what you're eating.
3. Read the low carb and atkins forums. There is a huge amount of valuable information here!
4. Exercise. It may not be fun, but it's necessary. There are plenty of us here that wish we had started earlier.
5. When it comes to cravings, procrastinate. Sometimes we just want that french fry, piece of candy (even sugar free is bad), or other little evil so bad! The most effective trick I've learned is to tell myself "maybe I'll have it in a little bit" or "maybe I'll have it after I do _______" It gives you time and space to get away from it while changing your focus so you don't do something you'll regret.
6. Weigh, measure, take a picture. These are great ways to track your progress and success. Sometimes we don't lose weight, but we're losing inches. And it's pretty amazing to see your before, during and after pictures.
Sorry, my list got long.

Hope this helps though. Welcome, and have fun!
