All or nothing mentality with my Protocol

I’m having a really hard time with getting past my all or nothing mentality when it comes to my Protocol.
I will write out my plans and when I eat or drink off my plan then my brain goes straight to- “Oh well, I guess I’ll just start tomorrow.” And then proceed to eat and drink whatever I want for the rest of the day.
This is the exact behavior I’ve struggled with in the past and I thought that doing Scholars was going to help me get past this cycle.
I’ve gotten coaching on this and I know that I’m allowing my primitive brain to take over. I know that I need to allow my urges but when it comes down to it, it feels like an automatic response to where Its happening before I even have time to realize what’s happening and allow the urge!
I’m really discouraged/ frustrated with myself and having a hard time being kind in my thoughts at this point.
