Glad to hear that you're owning it. Hopefully you tracked it to know exactly what it did to your carb counts. That can be very powerful.

For me the "I deserve it" mindset is one that I have to continually guard against, as it can lead me far astray. When I start to have that thought, I re-frame it to "I deserve to be fit and healthy" and that helps me to keep on course. I also try to identify the trigger of the "I deserve that pie" thinking. Is it that my dining companion is having it and it looks good, was the meal not satisfying, etc. For me, if I mindfully dissect it, I can usually keep my course and avoid the temptation. I will usually try to eat something that will provide some instant satiety, like a bit of heavy cream or avocado. Something rich, with good 'mouth feel'

Sounds like you have a good plan to get back on track, which is great, as sometimes one little slip can cause days, weeks or a more permanent slide.
