Belle, I just now noticed your post. I lost 45 pounds two years ago on Core and I, too, am struggling to keep it off. I needed to lose another 130 pounds so I had no business resting on my laurels.
Any how, we'd LOVE to have you hang out with us. We spend most of our time down on the threads on the Core board. Every week, we create a new weekly chat thread and there we talk about everything and anything but mostly our trials and tribulations with our Core program.
Please come join us there. We all know each other pretty well but we were all new at one time or another. So please jump in and get to know us. Here's the link for this week.

I'm getting ready to start over too and would enjoy the company and support.
