Both my husband and I have this problem. We'll get in these crazy endless snippy fights, until one of us goes, "Hey, did we eat anything today?".... The answer is usually a sheepish, "No."
it's hard when we both forget. He got used to not eating during his homeless childhood. I got used to not eating with a single mom who just didn't eat...to save $?
We haven't figured out exactly how to fix this starvation "habit" , but we try to remind each other, feed the other whenever we feed ourselves, and if we ever get our act together, we want to plan out meals for the whole week...
Gah! It's hard to live right without any template to follow
