Hi, Susan
Welcome to ADBB!
Hey, there's lots of us who have had to do Atkins more than once... as you can see from the stats in my siggie, I am one of them.

Let me be the first to tell you, YOU CAN DO THIS! I've been much more strict this time around, and it has paid off big time.
We even have a special forum where second-timers (or 3rd, 4th, etc.) can gather. It's called STAC (Second Time Around Club), and there are a great bunch of people there. Here is the link in case you haven't been there yet.
Second Time Around Club - Atkins Diet
Make sure to explore the board and use all that it has to offer. Good luck!
