Please hang in there Laura. Ride it out, the feeling will pass, I'm sure. Think of all the progress you have made! I like that quote above about how nothing tastes as good as thin feels. I am far from thin but nothing could taste as good as I feel today in my A-line skirt that was so tight I couldn't even wear it a few weeks ago. Think of all the progress you have made so far. 30 pounds - that's awesome!!! You don't want to mess that up, do you? Not to mention how bad you'll feel afterwards. I read a quote once that said it is easier to stay on the wagon than to fall off and get back up on it again.
I also carry a picture of me at my heaviest standing in front of the partner statute at MK. Whenever I start to feel my resolve going, I look at that picture and remember where I was just a few short weeks ago. Out of control and feeling lousy. That is what all those bad carbs will do to and for you. You already know what candy, ice cream, mash potatoes, rice and such taste like right? Those things will still be around once you reach your goal.
I also read something interesting from a guy on the lowcarbfriends site and he said that he had done well with Atkins and lost a ton of weight but then he started to get lax and cheat. His cheats led to a binge that lasted quite a bit of time. He said he kept telling himself he would get it together when things were easier (holidays over, etc.). I like what he said next, he said, it never gets easier. If we are waiting for things to get easier on us to loss the weight, we never will. Since it's never going to get easier, let's do this thing together. Okay?
