I can cheat a bit with no affects. That means a small roll or bread at a restaurant or small desert with sugar or wheat. But that happens less than once per month.
Yesterday I had real pizza for the first time this year. Had issues with it a few hours later. Feel fine today, but I usually will have some lower back pain/inflammation show up about 2 days later. Good news is that it doesn't spark any cravings. I just move on and I am fine.
I don't cheat much, but seriously for me, never ever having some foods, especially in a social setting would feel like a diet. Been there, done that, don't like it.
