I read an article related to stress/anxiety & food recently & believe it or not fortified cereal was listed as a stress-busting food that eases anxiety. Why?

I get warped cravings, too--more so now that my sense of taste & smell has been restored (happy 7 weeks cigarette-free, tomorrow!). On stable days, a little salad works (accompanied/topped with SF--my "magick mushroom" salads or "beet-nik meets zoo-chini" salads.

I had tons of calories left and really enjoyed the soy burgers I ate last night too. And yes, you can laugh your guts out, but I actually snack on stuff like green beans when I feel safe.
