For some reason, I'm just getting around to reading your question. I haven't used this CD yet (but I'm contemplating it), but I thought I'd share how starting a fitness or diet routine sometimes works for me--your post reminded me of some of the experiences I've had in the past.
As soon as I decide to "get with the program" I tend to...well, not really OVER eat, but eat things that I know won't be included once I've officially started. Sometimes it's not even foods I really like that much--potato chips, ice cream, brownies, etc. But I crave them, and I find that if I do eat them, poof--cravings are gone, and I can officially start.
The "pig out" part only lasts about a day, and I'm not sure if it's the reason why, but after I sort of get it out of my system, I don't have a problem staying with the fitness or diet program. After eating the junk food, healthy food tastes soooo good!
*And note, it's the same with fitness programs in a way--they are usually preceded by a day or a few days playing couch potato--and then I'm ready to go!
