Congrats on your success!
I don't know much about IP, but any program that says, I CAN'T have whatever, given, common sense, would not work for me.
How does IP support you, if you do not meet a time restricted goal? How does IP support easing you into a maintaining lifestyle?
I don't mean to rain on your parade or your current success, I really don't.
The thing is, do you want fast? Or forever?
Somewhere along the line we have to make a choice. We have to choose to make peace, with a lifestyle that is healthy, and still liveable.
Most days, you are on plan, you practice your chosen fitness program. But, at weddings, holidays, etc., you plan to give yourself a little lee way!
Knowing that you will get back in the saddle, asap.
