Hey @RandiW - I totally relate to this! I struggled to get my mind right for another Whole30 after completing my first one and had a few failures before getting myself mentally prepared.
One thing that helped me tremendously was sitting down and brainstorming on paper. I wrote down all the reasons I wanted to do another Whole30 and also thought about what benefits I experienced in my previous round. Something about writing it all out made everything click and helped me feel determined and committed.
Do you have It Starts with Food on audiobook? I wonder if listening to that might help?
