My SO can't seem to make a meal for less than 6, when it's usually the two of us, and may only have leftovers once, leading to a lot of waste, which irks me. Sometimes I'll eat more or less, depending on how I feel. It's also hard in that I'm a social eater, and although some foods are more problematic than others for me, she doesn't have issue with them. Example, legumes... I don't feel well, general muscle aches the next day, when I have them. I grew up with PB almost every day of my life until isolating the problem about 8 years or so ago. I still like the stuff, living in the southwest, beans are a typical side. I also still have it, it's just I live with the effect, or after a few days am more inclined to stop having it. Self control isn't always the easiest thing living and being around others.
