I, as well, try to keep my carbs around 50-75 for the same reasons. I also have to watch the nuts, can get crazy on those, then I'm guilt-tripping, then -- bam - I'm thinking and acting crazy and it happens so fast. Also agree with the fasting comment too.
Black-and-white and perfectionistic thinking is a big part of our problem, as I've noted from years of being in group therapy and OA meetings. I vividly remember a woman freaking the F out because she ate an extra banana. THIS is what makes us so unwell. Gotta let it go, man, as hard as it is.
