NaturalWonder,
I went 2 years no pizza no junk. You just get used to it. I think you can do it.
My mother in law lived with us and would always criticize the way we ate, so sort out of spite, I ate super clean. No cake, no pizza. The more she offered the more I did NOT want it.
Before you knew it 2 years went by.
My body was very tight year round!
