One word of advice: You might want to start when you have a day or two to stay in a place where you are absolutely comfortable. I have trouble passing gas with an audience (for example the bathroom at work has to be completely empty or I just can't do it). Well, during my first 2-3 days on the program my body was processing all that extra fiber and I had so much gas that the pressure in my belly was painful. By the end of day three, it had mostly subsided and by then I was feeling so great and energetic, I didn't care what "side effects" this program had.
Anyhoo, I would recommend trying the regular McD program because you can be assured that you will see drastic changes. After you're comfortable with the program, you can tweak it as you go. Good luck and if you do take that leap, these message boards are awesome. Also, post your planned exercise and daily menu at Roberta's corner because:
1) It helps you stick to what you had planned.
2) I get my best meal ideas from there
