Funny you should post this morning. I just read something and wonder if it could help you. Here's the URL: http://www.innertalk.com/Process_of_Change.html

I find that when I go off plan, it's because there is some inner voice giving me a wrong instruction. The last time I messed up it was a package of donuts that I just couldn't throw away. Having grown up poor, my inner voice was telling me it was bad to throw perfectly good food away.

Change is good for us, but it's hard when we are resistant. Finding that inner resistance will help you immensely in overcoming it. Good luck to you!
