Your family experience of straying off Protocol

I am wondering how you handled it when or if Christian (was it Christian?) strayed off the Protocol of no sugar, no flour when he was diagnosed insulin resistant? Did you talk to him, did he get right back on? What did you do?

The reason I ask is today is the first time I strayed really significantly and in testing my glucose tonight, it was quite high. Disappointed in myself. Feeling bad. Will get back in track in the morning for sure. This scared me.

Did you have to handle this with him? Thank you for your insight and all the coaching in here!
